Answer:
option d -1 is the answer
Answer:
f(x) = - 4x² + 24x - 20
Step-by-step explanation:
Given
f(x) = - 4(x - 3)² + 16 ← expand the factor using FOIL
= - 4(x² - 6x + 9) + 16 ← distribute parenthesis by - 4
= - 4x² + 24x - 36 + 16 ← collect like terms
= - 4x² + 24x - 20
Depending on what you're supposed to do, the three could either mean to distribute it into the equation, giving you
either
(3*2015) or (3*20)*(3*15) or (3*20) +/- (3*15)
Or an example of factoring where they took 3 out of 60 and 45.

Answer:
-4
Step-by-step explanation:
Point slope form: y - y = m (x - x)
5 - (-3) = m (-2 - 0)
5 + 3 = m (-2)
8 = m (-2)
m = 8/(-2)
m=4
