Answer:
The point of intersection gives the solution set(s) of the associated system.
Step-by-step explanation:
If we have a pair of simultaneous equations in 2 variables in x and y, then the point of intersection is the ordered pair (x,y).
This could be a unique intersection, only one point or infinitely many intersection.
This gives us the solution of the simultaneous equations.
Therefore the significance of the point of intersection of a pair of simultaneous equations is that, it gives us the solution set(s) of the associated system.

Answer:
The value of given expression is 1.
Step-by-step explanation:
Consider the given expression is
[tex]\dfrac{e}{4}+2f-3[/tex]
When e=12 and [tex]f=\dfrac{1}{2}[/tex].
Substitute e=12 and [tex]f=\dfrac{1}{2}[/tex] in the given expression.
[tex]\dfrac{12}{4}+2(\dfrac{1}{2})-3[/tex]
On simplification we get
[tex]3+1-3[/tex]
[tex]1[/tex]
Therefore, the value of given expression is 1.
The evaluated result of the expression e/4 + 2f - 3, given specific values e = 12 and f = 5, is 13.
To evaluate the expression e/4 + 2f - 3, we need to follow a systematic procedure. First, we replace 'e' and 'f' with their respective values or expressions, if provided. Once these values are substituted, we perform the mathematical operations in the given order: division, multiplication, and subtraction.
Assuming we have specific values for 'e' and 'f', let's say e = 12 and f = 5. Substituting these values into the expression, we get:
e/4 + 2f - 3
= 12/4 + 2 * 5 - 3
Now, we simplify each part of the expression step by step:
12/4 = 3 (division)
2 * 5 = 10 (multiplication)
3 - 3 = 0 (subtraction)
Summing up the simplified components, we get:
3 + 10 - 0
Finally, performing the remaining additions and subtractions:
3 + 10 = 13
13 - 0 = 13
So, when e = 12 and f = 5, the evaluated result of the expression e/4 + 2f - 3 is 13.

ABCD is a parallelogram. Segment AC = 4x + 10. Find the value of x and y.
Answer:
The values of x and y in the diagonals of the parallelogram are x=0 and y=5
Step-by-step explanation:
Given that ABCD is a parallelogram
And segment AC=4x+10
From the figure we have the diagonals AC=3x+y and BD=2x+y
By the property of parallelogram the diagonals are congruent
∴ we can equate the diagonals AC=BD
That is 3x+y=2x+y
3x+y-(2x+y)=2x+y-(2x+y)
3x+y-2x-y=2x+y-2x-y
x+0=0 ( by adding the like terms )
∴ x=0
Given that segment AC=4x+10
Substitute x=0 we have AC=4(0)+10
=0+10
=10
∴ AC=10
Now (3x+y)+(2x+y)=10
5x+2y=10
Substitute x=0, 5(0)+2y=10
2y=10
[tex]y=\frac{10}{2}[/tex]
∴ y=5
∴ the values of x and y are x=0 and y=5

Answer:
Hours inequality (solution set): 0 ≤ x ≤ 7
Cost inequality: $2 ≤ y ≤ $100
Step-by-step explanation:
The babysitter charges $14 dollars per hour + bus fare
Price per hour = $14
Bus fare = $2
Mr. Tyler wants to spend no more than $100
Subtract the bus fare from the total amount, as that will not contribute to the babysitter's hours
$100 - $2 = $98
Divide by $14 per hour
$98 ÷ $14 = 7 hours
The maximum amount of time that Mr. Tyler could hire the babysitter for is 7 hours
This means that the hours cannot be greater than 7. It is given that x cannot be less than 0, because the babysitter cannot work negative hours.
0 ≤ x ≤ 7
This inequality shows that the Mr. Tyler will not have the babysitter work for less than 0 hours, or more than 7 hours. He will have to pay $2 minimum, or $100 max. Below is the inequality to represent this:
(y represents amount Mr. Tyler will pay)
$2 ≤ y ≤ $100

4. The coordinates of the vertices of rectangle
ABCD are A(3,-2), B(3, 2), C(-3, 2), and
D(-3, -2).
a. Rectangle ABCD is rotated 90° about the
origin. What are the coordinates of the
vertices of rectangle A'B'C'D'?
b. What are the measures of the angles of
A'B'C'D'?
Answer: a) A'=(2, 3), B'=(-2,3), C'=(-2,-3) D'=(2,-3)
b) the measure of each angle is 90 degrees.
Step-by-step explanation:
a) To find the coordinates you need to know that (x,y) is changed to (-y,x). This means that they are flipped and changed from either negative to positive or positive to negative.
b) Each angle is 90 degrees because that shape is a rectangle with all equal right angles.
The coordinates of the vertices of rectangle A'B'C'D' after rotating rectangle ABCD 90° about the origin are A'(-2,-3), B'(-2,3), C'(-2,-3), and D'(2,-3). All angles in rectangle A'B'C'D' measure 90°.
Explanation:When a point is rotated 90° about the origin, the new coordinates can be found using the formula (y, -x). Therefore, applying this to each vertex of the rectangle, A'(3,-2) becomes A'(-2,-3), B'(3, 2) becomes B'(-2,3), C'(-3, 2) becomes C'(-2,-3) and D'(-3, -2) becomes D'(2,-3).
Since A'B'C'D' is a rectangle, all its angles are right angles. This means all the angles measure 90°.

–2(5n + 7) + 8n = 2(1 – 3n)
Answer:
n = 4
Step-by-step explanation:
Solve using the distributive property. This means you can multiply the number outside the brackets with each number inside the brackets. Then isolate "n" by moving all other numbers to the right side, leaving "n" alone on the left.
–2(5n + 7) + 8n = 2(1 – 3n) Distribute
(5n)(-2) + (7)(-2) + 8n = (1)(2) – (3n)(2) Multiply with each number in brackets
–10n + (–14) + 8n = 2 – 6n Remove brackets around –14
–10n – 14 + 8n = 2 – 6n Adding a negative is subtracting it's positive
–14 –2n = 2 – 6n
–14 + 14 –2n = 2 + 14 – 6n Add 14 to both sides
–2n = 16 – 6n
–2n + 6n = 16 – 6n + 6n Add 6n to both sides
4n = 16
4n/4 = 16/4 Divide both sides by 4
n = 4 Solved for "n"
Check answer by substituting "4" whenever there is "n" in the original equation. Then solve each side.
–2(5n + 7) + 8n = 2(1 – 3n)
–2(5(4) + 7) + 8(4) = 2(1 – 3(4)) Solve inside brackets

K = 4D. K = D + 6
4D = D + 6
-D. -D
3D = 6
3. 3
D = 2
Answer:
d=2
Step-by-step explanation:
We can use the given information to write down two equations that describe the ages of Kevin and Daniel.
Let Kevin's current age be k and Daniel's current age be d.
k=4d
k=d+6
Now we have two independent equations, and we can solve for our two unknowns.
Since we are looking for d, and both of our equations have k alone on one side, this is a convenient time to use elimination.
Subtracting the second equation from the first equation, we get:
0=4d-(d+6)
which combines the information about d from both of our original equations.
Solving for d, we get: 3d = 6.
d=2
Sanchez applied 6 fluid Ounces of an herbicide per acre on 300 acres of com. How many gallons
did he apply
Click here to enter text.
Answer:
Sanchez applied 1,800 fluid ounces of herbicide to his 300 acres of corn.
Step-by-step explanation:
Let's identify what we already know:
1) Sanchez has 300 acres of corn
2) For every 1 acre, Sanchez applies 6 fluid ounces of an herbicide.
So, we need to figure out how many fluid ounces Sanchez used for the entire six acres. We can create a formula for this:
300 acres x 6 fluid ounces = x
x equals total number of fluid ounces. We multiple the number of acres by the fluid ounces, to get 1,800 fluid ounces for the entire 300 acres of corn.
Final answer:
Sanchez applied a total of 14.0625 gallons of herbicide on 300 acres of corn, after converting the total amount of herbicide from fluid ounces to gallons using the equivalence of 1 gallon equal to 128 fluid ounces.
Explanation:
Sanchez applied 6 fluid ounces of herbicide per acre on 300 acres of corn. To determine how many gallons he applied, we'll use the unit equivalence that 1 gallon = 128 fluid ounces. First, we'll calculate the total amount of herbicide in fluid ounces by multiplying the rate of application by the number of acres:
6 fluid ounces/acre imes 300 acres = 1800 fluid ounces total.
Next, we'll convert fluid ounces to gallons:
1800 fluid ounces imes (1 gallon / 128 fluid ounces) = 14.0625 gallons.
Therefore, Sanchez applied 14.0625 gallons of herbicide on the 300 acres of corn.

Which statement describes the graph of f(x) = x² - 6x + 9?
a line with an x-intercept of (-3, 0)
a parabola with an x-intercept of (-3, 0)
a line with an x-intercept of (3, 0)
a parabola with an x-intercept of (3, 0)
Answer:
A parabola with an x-intercept of (3, 0)
Step-by-step explanation:
We can immediately rule out the first and third options, because the equation of a second degree function is a parabola.
Your equation is
ƒ(x) = x² - 6x + 9 = 0
We can factor this equation as
ƒ(x) = (x - 3)²
The parent parabola, y = x², has its x-intercept at (0,0).
Your function subtracts three from x, so the intercept is shifted three units to the right.
The graph of your function is a parabola with an x-intercept of (3, 0).
The figure below shows the graph of your function shifted three units by subtracting three from x.

Find the total surface area of a square based prism (cuboid) of height 4cm, given that the side length of its base is 6cm.
please show working out
Total surface area of the square pyramid is 1476 cm².
Step-by-step explanation:
Step 1:Total surface area of a pyramid = 12pl + B. Here p is perimeter of the base which is a square = 4 × side, l is the slant height and B is the area of the base = side²
Step 2:Find perimeter of the base
⇒ p = 4 × side = 4 × 6 = 24 cm
Step 3:Find the slant height of the prism. l² = height² + (side/2)² (Based on Pythagoras Theorem)
⇒ l² = 4² + (6/2)² = 16 + 9 = 25
⇒ l = √25 = 5 cm
Step 4:Find the area of the base of the pyramid.
⇒ B = side² = 6² = 36 cm²
Step 5:Calculate total surface area of the pyramid.
⇒ TSA = 12 × 24 × 5 + 36 = 1440 + 36 = 1476 cm²

Jesse finished the first race in two minutes and seven seconds. Tim finished 12 seconds faster than Jesse. Juan finish eight seconds faster then Tim. How long did it take Juan to finish.
To find out how long it took Juan to finish, we add the time differences to Jesse's time. Tim finished 12 seconds faster than Jesse and Juan finished 8 seconds faster than Tim.
Explanation:To find out how long it took Juan to finish, we need to add the time differences to Jesse's time. First, we know that Tim finished 12 seconds faster than Jesse, so we can add 12 seconds to Jesse's time which becomes 2 minutes and 19 seconds.

The graph of the equation [tex]f(\dfrac{1}{4}x)=\dfrac{1}{4}x+1[/tex] has a slope of 1/4 and y-intercept of 1.
What is the graph of a linear equation.
The graph of a linear equation is a straight line graph. It can be expressed as function of x i.e. f(x) = y = mx + b.
Given that: f(x) = x + 1, we are to graph the function of f(1/4x). We will have to replace (1/4x) into the original equation.
[tex]f(\dfrac{1}{4}x)=\dfrac{1}{4}x+1[/tex]
It implies that the graph of f(1/4x) has a slope of 1/4 and the y-intercept is 1. So it will be less steeper than the equation f(x) = x + 1.
Mateo has drawn a line to represent the parallel cross-section of the triangular prism. Is he correct? Explain.
Answer:
No
Step-by-step explanation:
A triangular prism has a uniform cross-section.A parallel cut of the solid will produce a cross section which is parallel to the triangular base.
A right prism contains uniform cross-sections, meaning the area of each cross-section is the same.
In this case, the position of the line indicating a cut will not produce polygons congruent to the base.

The trip would cost $23.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 4 - 9 is an equation.
We have,
Taxi A:
c = 3.5d + 2
Taxi B:
c = 3d + 5
Where c is the cost of the taxi after d distance.
Now,
The cost of the taxi is the same.
3.5d + 2 = 3d + 5
3.5d - 3d = 5 - 2
0.5d = 3
d = 3/0.5
d = 30/5
d = 6
The cost of the taxi at d = 6.
c = 3.5d + 2 = 3.5 x 6 + 2 = 21 + 2 = 23
c = 3d + 5 = 3 x 6 + 5 = 18 + 5 = 23
Thus,
The cost of both taxis is the same after 5 miles.
