Answer: The first one : -2x^2 + 20x - 54
Step-by-step explanation:
y = -2(x-5)^2 - 4
= -2(x^2 - 10x + 25) - 4
= -2x^2 + 20x - 50 - 4
= -2x^2 + 20x - 54
Answer:
9x does

remind me if its wrong
Answer: w = 13 m, L = 19.5 m
<u>Step-by-step explanation:</u>
P = 3w + 2L
3w + 2L = 78
2L = 78 - 3w
A = w · L
a=-3/2 b=39
Answer:
A y < -1/2
Step-by-step explanation:
4/3 < -8/3 y
Multiply both sides by 3
3×4/3 < 3× -8/3 y
4 < - 8y
Divide both sides by -8
4/-8 > -8y/-8
The inequality sign changes by dividing by negative
-1/2 > y is same as y < -1/2
Therefore
y < -1/2
