Answer:
x ≤ 7
Step-by-step explanation:
(2x-4) + 110 ≤ 120
Combine like terms
2x +106 ≤ 120
Subtract 106 from each side
2x+106 -106 ≤ 120-106
2x ≤ 14
Divide each side by 2
2x/2 ≤ 14/2
x ≤ 7
The area = 1/2 * base * height
202.5 = 1/2 * base * 15
measure of the base = 202.5 / (1/2 * 15)
= 27 answer
Answer:
y = -3/8(x + 2)^2 + 8
Step-by-step explanation:
vertex form is
y = a(x - b)^2 + c where a is a constant and (b,c) is the vertex.
The maximum is at (-2, 8) because x 8 = height and x =-2 is equn. of symmetry
So here we have
y = a(x - (-2))^2 + 8
y = a(x + 2)^2 + 8
Now at the point (-6, 2):
2 = a(-6+2)^2 + 8
2 = 16a + 8
16a = -6
1 = -3/8.
So our equation is y = 3/8(x + 2)^2 + 8
