Answer:
Step-by-step explanation:
-3x + 9y = -24
3x + 3y = 24
12y = 0
y = 0
-3x + 9(0) = -24
-3x = -24
x = 8
(8,0)

The correct answer is option D
Step-by-step explanation:
Number of yarns purchased by Rebecca ![= 6\\](https://tex.z-dn.net/?f=%3D%206%5C%5C)
Cost of one yarn ![= 3.95\\](https://tex.z-dn.net/?f=%3D%203.95%5C%5C)
Cost of 6 yarn ![= 6 * 3.95\\](https://tex.z-dn.net/?f=%3D%206%20%2A%203.95%5C%5C)
Cost of 6 yarn after discount of
%
![= 6 * 3.95 * 0.8\\](https://tex.z-dn.net/?f=%3D%206%20%2A%203.95%20%2A%200.8%5C%5C)
Cost after tax of 8%
![(6 * 3.95 * 0.8) + 0.08 (6 * 3.95 * 0.8)\\= 1.08 (6 * 3.95 * 0.8)\\](https://tex.z-dn.net/?f=%286%20%2A%203.95%20%2A%200.8%29%20%2B%200.08%20%286%20%2A%203.95%20%2A%200.8%29%5C%5C%3D%201.08%20%286%20%2A%203.95%20%2A%200.8%29%5C%5C)
<h3>Solution for 9x-17=4x+28 equation:</h3>
Simplifying
9x + -17 = 4x + 28
Reorder the terms:
-17 + 9x = 4x + 28
Reorder the terms:
-17 + 9x = 28 + 4x
Solving
-17 + 9x = 28 + 4x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-4x' to each side of the equation.
-17 + 9x + -4x = 28 + 4x + -4x
Combine like terms: 9x + -4x = 5x
-17 + 5x = 28 + 4x + -4x
Combine like terms: 4x + -4x = 0
-17 + 5x = 28 + 0
-17 + 5x = 28
Add '17' to each side of the equation.
-17 + 17 + 5x = 28 + 17
Combine like terms: -17 + 17 = 0
0 + 5x = 28 + 17
5x = 28 + 17
Combine like terms: 28 + 17 = 45
5x = 45
Divide each side by '5'.
x = 9
Simplifying
x = 9
Answer:
Hello
9x+7=2x+98(Vertically Opposite Angles)
9x-2x=98-7
7x=91
x=91/7
x=13
(9x+7)=9(13)+7
=117+7
=124
y+124=180(linear pair)
y=180-124
y=56
