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:
108
Step-by-step explanation:
36(3)=108
The correct answer is not on the answer choice.
Whichever answer is the closest to 108, choose it.
Q= - 1/3 is the answer-move the negative sign to the left multiply both sides by 7q then cancel 7 then finally divide both sides by 3. Hope this helps
Answer:
6n−7n−4+n+10
=6n+−7n+−4+n+10
Combine Like Terms:
=6n+−7n+−4+n+10
=(6n+−7n+n)+(−4+10)
=6
Answer:
=6
Step-by-step explanation:
Answer:
y = -2x + 3
Step-by-step explanation:
y = mx + b
slope = m
m = y2 - y1/x2 - x1
-3 - 3/3 - 0 = -6/3
m = -2
y = -2x + b
b = y-intercept
b = 3
y = -2x + 3
