-2x-y=1
y=3x-1
Answer:
x=-2/5
y=-1/5
Step-by-step explanation:
[tex]-2x-y=1\\y=3x-1[/tex]
Get the y variables onto 1 side
[tex]y+1=-2x\\y=3x-1[/tex]
Now shift the 1 over
[tex]y=-2x-1\\y=3x-1[/tex]
To solve for x, we can subtract the second equation from the first equation
[tex](y-y)=-2x-3x-1-1 = 0=-5x-2\\5x=-2\\x=-2/5[/tex]
Plug back into the first equation we found and solve for y
[tex]y=-2x-1\\y=-2(-2/5)-1\\y=4/5-1=-1/5[/tex]
Kara works at a fine jewelry store and earns commission on her total sales for the week. Her weekly paycheck is $6,500 including her salary which is $1,000. Her sales for the week totaled to $45,000. Express her rate of commission as a percent rounded to the nearest whole number.
Rate of commission as a percent is 12 %
Solution:
Kara weekly paycheck is $6,500 including her salary which is $1,000
Therefore,
Commission amount = Weekly paycheck - salary
Commission amount = 6500 - 1000
Commission amount = 5500
Her sales for the week totaled to $45,000
Therefore rate of commission is given as:
[tex]Commission\ rate = \frac{\text{commission amount}}{\text{sales for week}} \times 100[/tex]
Substituting the values we get,
[tex]Commission\ rate = \frac{5500}{45000} \times 100\\\\Commission\ rate = \frac{550}{45}\\\\Commission\ rate = 12.2 \approx 12[/tex]
Thus rate of commission as a percent is 12 %

Dilly is 7 years younger than Dally. In 4 years time she will be half Dally’s age. What is the sum of their ages now?
Answer:
The sum of their ages now is 13
Step-by-step explanation:
Dally's age = x
Dilly's age = x - 7
In 4 years time Dilly will be half Dally’s age, therefore:
Dilly's age plus four equals to half of Dally’s age plus four,
replacing with the values and variables we know:
x - 7 + 4 = (x + 4) /2
x - 3 = (x + 4) /2
2x - 6 = x + 4 (Multiplying by 2 at both sides)
2x - x = 4 + 6 (Like terms)
x = 10 ⇒ x - 7 = 3
The sum of their ages now is 13 (10 + 3)
The sum of their ages now is 13 years
Let the age of Dilly be "x"
Let the age of Dally be "y"
If Dilly is 7 years younger than Dally, then;
x = y - 7 ....... 1
In 4 years time, their age will be:
Dilly = x+ 4
Dally = y + 4
If in 4 years' time she will be half Dally’s age, then;
x+4 = 1/2(y+4) ............... 2
Substitute equation 1 intp 2 to have:
y-7+4 = 1/2(y+4)
y - 3 = 1/2(y+4)
2y - 6 = y + 4
2y - y = 6 + 4
y = 10
Recall that x = y - 7
x = 10 - 7
x = 3
Sum of their ages will be x + y = 10 + 3 = 13 years
Hence the sum of their ages now is 13 years

In a right triangle, side a is 3 times as long as side b, and side c is 30 cm. Using the Pythagorean Theorem, what are the lengths of sides a and b? Round your answers to the nearest tenth.Hypotenuse is 30,A and B are not known but we know A is 3 times more than B.
Answer:
a = 3√10 ≈ 9.5b = 9√10 ≈ 28.5Step-by-step explanation:
We are given two relations we can use to find "a" and "b":
a = 3b
a² + b² = 30²
Substituting for "a", we have ...
(3b)² +b² = 900
10b² = 900
b² = 90
b = √90 = 3√10 ≈ 9.5
Then "a" is ...
a = 3b = 3(3√10) = 9√10 ≈ 28.5
The values of "a" and "b" are about 28.5 and 9.5, respectively.
Julia went into a movie theater and bought 2 bags of popcorn and 5 pretzels, costing
a total of $37.25. Zoe went into the same movie theater and bought 8 bags of popcorn
and 9 pretzels, costing a total of $102.25. Determine the price of each bag of popcorn
and the price of each pretzel.
Answer:
A bag of pop corn costs $8, and each Pretzel costs $4.25.
Step-by-step explanation:
Let [tex]b[/tex] be the price of popcorn, and [tex]p[/tex] the price of Pretzels. If the girl bought 2 bags of popcorn and 5 Pretzels and it cost her $37.25, we have the equation
[tex]2b+5p=37.25[/tex] (this says that the cost of 2 popcorn bags plus 5 pretzels equals $37.25) .
And, since Zoe bought 8 popcorn bags and 9 Pretzels with a total price of $102.25, we get the equation
[tex]8b+9p=102.25[/tex] (this says that the cost of 8 popcorn bags plus 9 Pretzels equals $102.25).
Thus, we have two equations
1. [tex]2b+5p=37.25[/tex]
2. [tex]8b+9p=102.25[/tex]
and we solve them by first multiplying equation (1) by 4:
[tex]4(2b+5p=37.25 )\rightarrow (8b+20p=149)[/tex],
and then subtracting it from equation (2):
[tex]\:\:\:\:\: 8b+9p=102.25\\-(8b+20p=149)\\\line(1,0){3 cm}\\-11p=-46.75\\\\\boxed{p=\$4.25}[/tex]
Now we put this value of [tex]p[/tex] into equation (1) and get:
[tex]2b+5(4.25)=37.25[/tex]
and we solve for [tex]b[/tex] to get:
[tex]2b=37.25-21.5[/tex]
[tex]\boxed{ b=8}[/tex]
Therefore, a bag of popcorn costs $8, and each Pretzel costs $4.25.

8 is your answer

3 lines are shown. A line with points M, H, K intersects with a line with points J, H, L at point H. Another line extends from point H to point N in between angle K, H, J. Angle M H L is (3 x + 20) degrees, angle K H N is (x + 25) degrees, and angle J H N is (x + 20) degrees. What is the measure of AngleJHN? 25° 45° 50° 95°
Answer:
Option B.
Step-by-step explanation:
Given information: ∠MHL=(3x+20), ∠KHN=(x+25), and ∠JHN=(x+20).
We need to find the measure of ∠JHN.
[tex]\angle MHL=\angle JHK[/tex] (Vertical opposite angles)
[tex]\angle MHL=\angle JHN+\angle KHN[/tex]
Substitute the given values.
[tex]3x+20=(x+20)+(x+25)[/tex]
[tex]3x+20=2x+45[/tex]
[tex]3x-2x=45-20[/tex]
[tex]x=25[/tex]
The value of x is 25. So, the measure of ∠JHN is
[tex]\angle JHN=x+20=25+20=45[/tex]
The measure of ∠JHN is 45°.
Therefore, the correct option is B.
Answer:

The segments shown below could form a triangle 6 5 12
Answer:
no
Step-by-step explanation:
6 and 5 are the smaller sides but they only add to 11
the need to get to something higher than 12
no equal or less than
Final answer:
Segments 6, 5, and 12 cannot form a triangle because the length of one segment (12) is equal to the sum of the other two (6 + 5), which violates the Triangle Inequality Theorem.
Explanation:
The question involves determining whether three given segments can form a triangle. To form a triangle, the sum of the lengths of any two sides must be greater than the length of the third side. This is known as the Triangle Inequality Theorem. Given the segments 6, 5, and 12, we can test this theorem:
6 + 5 > 12? (No, because 11 is not greater than 12)6 + 12 > 5? (Yes, because 18 is greater than 5)5 + 12 > 6? (Yes, because 17 is greater than 6)Since one of the conditions fails, the segments 6, 5, and 12 cannot form a triangle. Visually, it's also clear that one segment (12) is as long as the sum of the other two (6 + 5), which means they could only form a straight line, not a triangle.

Given the sequence 2, 4, 8, , 16,........, where x = 0, 1, 2, 3, .......what is the function rule? f(x) = 2x + 2 f(x) = 2(2)x f(x) = (2x) f(x) = 2
Option C: [tex]f(x)=2^x[/tex] is the function rule.
Explanation:
The sequence is [tex]2,4,8,16, \dots \dots[/tex]
Let us find the common difference of this sequence.
Common ratio = [tex]\frac{4}{2} =2[/tex]
Hence, [tex]r=2[/tex]
Thus, the given sequence is a geometric progression.
To determine the function rule, let us substitute the values in the general formula of GP which is given by
[tex]f(x)=ar^{x-1}[/tex] where [tex]a=2, r=2[/tex]
Substituting we get,
[tex]f(x)=2(2)^{x-1}[/tex]
Simplifying, we get,
[tex]f(x)=2\times2^x\times2^{-1[/tex]
Adding the powers, we get,
[tex]f(x)=2^{1+x-1}[/tex]
Simplifying, we get,
[tex]f(x)=2^x[/tex]
Hence, the function rule is [tex]f(x)=2^x[/tex]
Thus, Option C is the correct answer.

the two vertices of a triangle are (0,6) and (0,12). if the are of the triangle is 12 square units, where can the third vertex be? What if the triangle is also isosceles?
Answer:
1) (4,6),(-4,6), (4,12),(-4,12)
2) (4,9) or (-4,9)
Step-by-step explanation:
Observe that the two vertices given, (0,6) and (0,12) are on the y-axis.
The distance between this points is |12-6|=6
We know area of a triangle is [tex]A=\frac{1}{2}bh[/tex]
We were given area as 12.
[tex]\frac{1}{2}*b*6=12[/tex]
[tex]3b=12[/tex]
b=4 units
We can find a point 4 units horizontally away from any of the vertex.
So (4,6),(-4,6), (4,12),(-4,12) are feasible vertices.
For the triangle to be isosceles, then the third vertex must be on the horizontal line through the midpoint of (0,6) and (0,12) and must be 4 units away from the line x=0.
Therefore if thr triangle is isosceles, then third vertex must be at (4,9) or (-4,9)

Graph the solution to the scenario by dragging and dropping a circle/arrow onto the number line.
The roots of Billy's plant grew to 3 inches beneath Earth’s surface. Graph all the possible depths the roots can continue to grow.
Step-by-step explanation:
"At least x" means "that value x or more"
"At least 2" means "2 or more"
So Billy's plants grow 2 inches or more a month. The smallest increase possible is 2 inches.
We plot a closed circle at 2 on the number line. The closed circle tells us "include this value in the solution set". In contrast, the open circle says "exclude the endpoint from the solution set"
Then we shade to the right indicating all of the possible outcomes (growing 3 inches, growing 4 inches, etc.).

Answer:
12 centimeters
Step-by-step explanation:
An isosceles triangle has two congruent sides which are legs(2 sides having same length )If x is length of each leg, then we ca write the equation like this
equation: x+x+8=32
combine like terms
2x +8 = 32
minus 8 from each side
2x=32-8
2x=24
divide both sides by 2
2x/2 = 24/2
x=12 centimeters
