Answer:
vertex = (- 2, - 36)
Step-by-step explanation:
Given a parabola in standard form : y = ax² + bx + c : a ≠ 0
Then the x- coordinate of the vertex is
= - 
f(x) = 5x² + 20x - 16 is in standard form
with a = 5, b = 20 and c = - 16
= - 
= - 2
Substitute x = - 2 into f(x) for corresponding y- coordinate
f(- 2) = 5(- 2)² +20(- 2) - 16 = 20 - 40 - 16 = - 36
vertex = (- 2, - 36)
Answer: 45x3x345!3
Step-by-step explanation:
you multiply all numbers then you divide by all the numbers there and there’s your answer
Make the 3 into a fraction and then flip it to cancel out which makes it easier then do it to the -2,197 for you to get x
Answer:
7
Step-by-step explanation:
n! Might be 7, and n might be 6. r might also be 6. So 6 - 6= 0! = 1
So I think it might be 7 ÷ 1, which is 7.
