Answer:

y = - 8x + 9

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c

Given

8x + y = 9 ( subtract 8x from both sides )

y = - 8x + 9 ← in slope- intercept form

The required slope intercept of the given equation of the line is given as y = -8x + 9.

The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.

The equation is the relationship between variables and represented as y = ax + b is an example of a polynomial equation.

Here,
Given the equation of the line,
8x + y = 9,

Rearrange the equation in slope intercept form,
y = -8x + 9

Thus, the required slope intercept of the given equation of the line is given as y = -8x + 9.

Answer:

C: Graph A is a linear function and Graph B is also a function but a low and high constant rate

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.

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

Answer:

If Ty can make 7 signs in 2 hours that means in 4 hours he could double that output to make 14 signs. Harrison, on the other hand, makes 15 signs every 4 hours. Therefore, by default - Harrison makes 1 more sign every 4 hours than Ty. Harrison has the greater rate. You have to figure out how many signs Ty can make in 4 hours, by multiplying 2 x 7 = 14.

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

–2(20 + 7) + 32 = 2(1 – 12)         Distribute

(20)(–2) + (7)(–2) + 32 = (1)(2) – (12) (2)        Multiply where necessary

–40 + (–14) + 32 = 2 – 24        Simplify

–22 = –22        Same answer

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.

Answer:

(3 , 2.5)

the trip would cost $12.5

12.5 = 3.5 (3)+2

12.5 = 3 (2.5)+5

Step-by-step explanation:

The distance at which the cost of each taxi is the same is 6 miles.

The trip would cost $23.

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.

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.

Answer:

6.7

Step-by-step explanation:

the tenths place is one spot after the decimal

The monthly payment for the loan of $1500 with $92.81 interest over 9 months is $176.98.

To calculate the monthly payment for a $1500 loan with $92.81 in interest over 9 months, we must first find the total amount to be paid back, which includes both the principal and the interest. The total repayment amount will be $1500 (the original loan) plus $92.81 (the interest), making the total amount $1592.81.

We can then divide this total amount by the number of months the loan will be held to find the monthly payment:

Monthly Payment = Total Repayment Amount ÷ Total Months

Monthly Payment = $1592.81 ÷ 9

Monthly Payment = $176.98

Therefore, the student needs to pay $176.98 every month to pay off the loan in 9 months.

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.

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

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]

Answer:

15/2

Step-by-step explanation:

y varies directly as x can be written as:

y & x

y = Kx

K = y/x

But from the question, we were told that:

y = 10

X = 20

K = y/x

K = 10/20

K = 1/2

The formula for the expression is:

y = Kx

y = 1/2 x

Now let us solve for y, when:

x = 15

y = 1/2 x

y = 1/2 x 15

y = 15/2

Final answer:

To find the value of y when x = 15, we first determined the constant of proportionality (k) using the given y and x values, which was found to be 0.5. We then plugged x = 15 into the direct variation formula y = kx, resulting in y = 7.5.

Explanation:

If y varies directly with x and y = 10 when x = 20, then we can write this direct variation as y = kx, where k is the constant of proportionality. To find k, we substitute the known values of x and y and solve for k:
10 = k × 20
k = 10 / 20
k = 0.5
With k found, we can now determine what y is when x = 15:

y = k × x
y = 0.5 × 15
y = 7.5
