Answer:
(x-8y)^2
Step-by-step explanation:
I used a calculator
I have no clue what to answer 9
Answer:
Z = 34
Step-by-step explanation:
From the series, we have that:
a = -2
a + d = 7
Hence, -2 + d = 7
∴ d = 7 + 2 = 9
a + 2d = X; a + 3d = Y and a + 4d = Z
-2 + 4(9) = Z
∴ Z = 36 - 2 = 34
Answer:

Step-by-step explanation:
Given

Rewrite to show y-intercept
We have: 
Subtract x from both sides

Divide both sides by z

<em>The y intercet is: </em>
