45+55=100 180-100=80 that makes y = 80, and vertical angles makes x=80
Answer: I'm pretty sure its 483c try it
Step-by-step explanation:
Dont know but mabye someone who is not 8 will know
F(x) = -(x+7)² + 4
f(x) = -(x+7)(x+7) + 4
f(x) = -(x² + 7x + 7x + 49) + 4
f(x) = -x² - 14x - 49 + 4
f(x) = -x² - 14x - 45
True for f(x)
