Answer:Wednesday I think
Step-by-step explanation:
Find the vertex: -4x^2 + 16x - 7
Vertex = ( x, f(x)).
x = -b/2a
x = -16/2(-4)
x = -16/-8
x = 2
f(x) = -4x^2 + 16x - 7
Let x = 2
f(2) = -4(2)^2 + 16(2) - 7
f(2) = -4(4) + 32 - 7
f(2) = -16 + 32 - 7
f(2) = 16 - 7
f(2) = 9
Vertex = (2, 9)
Answer:
Step-by-step explanation:
So 8 times what is 5?
8 times x=5
x=0.625
Since trevon bought one package for 3 dollars than 3 x 21 equals 63
Answer = 21
I think it’s 5 because I think it’s 6
