Answer:
x = 1
y = - 1
Step-by-step explanation:
-8x - 3y = -5
-2x + 7y = -9 | × (-4)
-8x - 3y = - 5
8x - 28y = 36 +
________________
- 8x + 8x - 3y - 28y = - 5 + 36
- 31y = 31
31y = - 31
y = - 1
- 8x - 3(-1) = - 5
- 8x + 3 = - 5
- 8x = - 8
8x = 8
x = 1
You can use the distibutive property by breaking apart the bigger number (38) into 30 and 8. Now, you can do: (9 x 30) + (9 x 8)
I hope this helps!!!
:D
if x = 3
3 > -1, and so you use the x² formula.
Plug in 3 for x
x² = (3)²
Simplify
3² = 3 x 3 = 9
9, or (A), is your answer
hope this helps
