Answer: Classmate is wrong. Vertex = (-2, -4)
Step-by-step explanation:
The vertex form of a quadratic equation is: y = a(x - h)² + k where
- "a" is the vertical stretch
- -a is a reflection over the x-axis
- h is the horizontal shift (positive = right, negative = left)
- k is the vertical shift (positive = up, negative = down)
Given: g(x) = -5(x + 2)² - 4
↓ ↓
h= -2 k= -4
Vertex = (-2, -4)
Answer:
w=6
Step-by-step explanation:
P=2(L)+2(w)
48= 2(18)+2w
48=36+2w
12=2w
w=6
checking;
48= 2(18)+2(6)
48= 36+12
48= 48
Answer:45
Step-by-step explanation:5(7)+5(2)=35+10=45.This is an example of expansion or distributive expression
Answer:
116 = 116.
Step-by-step explanation:
Because the equations are the same, x + 4, they will always be equal to each other. 4 + 112 = 116.
