Answer:

Step-by-step explanation:

8x + 8y = 2 -------(1)

8x + 5y = 1 -------(2)

subtract equation (2) from equation (1)

The 8x will be eliminated, leaving us with;

3y = 1

Divide bothside of the equation by 3

y = 1/3

substituting y = 1/3 in equation (1)

8x + 8y = 2

8x + 8(1/3) = 2

8x + 8/3 = 2

subtract 8/3 from both-side

8x + 8/3 -8/3 = 2 -8/3

8x = 2 - 8/3

8x = 6 - 8 / 3

8x = - 2/3

Divide both-side of the equation by 8

8x / 8 = -2/3 ÷ 8

x = -2/3 × 1/8

x = -1 / 12

Rudiy27
I think the correct answer from the choices listed above is the first option. The statement that is true for every rotation would be that the image and pre-image are congruent. A<span>ll the rest deals with changing the rotated shape not a constant. Hope this helps.</span>

What equation shows 10x-2y=10 in slope intercept form
Vesna [10]
10x-2y=10 We need to solve this equation for "y" to put it into slope intercept form:

10x-2y=10
-2y = -10x +10 Subtracted 10x from both sides
y = 5x - 5 Divided both sides by -2

y = 5x - 5 Is slope intercept form
