Answer:
Step-by-step explanation:
In order to solve for x, she had to first subtract 6 on both sides of the equation. Then divide by 5 on both sides of he equation. After the division part, she was able to successfully isolate x.
The equation she had to solve was (C) 5x+6=21
First step: Subtracting 6 on both sides of equation resulted in
5x = 15
Second step: Dividing both sides of the equation by 5 resulted in
x = 3
These equations are already in vertex form. So, we can easily find the vertex of each equation.
f(x) = -(x-1)^2 - 2
Vertex: (1,-2)
The vertex in this equation is the maximum because it faces down (a=-1).
g(x) = (x+2)^2 + 1
Vertex: (-2,1)
The vertex in this equation is the minimum because it faces up (a=1).
Answer:
6.25
Step-by-step explanation:
V=lwh
/3
To account for the 2/3 slant, add 1
2.5X2.5X3/3 = 6.25
If this is incorrect, I'm sorry. But this seemed to be the most plausible answer based on how far away the other numbers are and how it matches perfectly with the answer choice
Answer: i believe it would be 5 if not i’m sorry.
