30. is 8 [-5] [3] [-2] -2
Answer:
-9
Step-by-step explanation:
2(-x)² - 5 = 157
2x² - 5 = 157
add 5 to each side of the equation:
2x² = 162
divide both sides by 2:
x² = 81
√81 = 9 or -9
Answer:
y = -5/4x - 4
Step-by-step explanation:
Plug in 6 for y and -8 for x. Then solve for b or "y-intercept". You should get -4
