Answer:
y = -2x^2 -4x +1
Step-by-step explanation:
y-3 = -2 (x+1)^2
Foil (x+1)^2
(x+1)(x+1) = x^2 +x+x+1 = x^2 +2x+1
Substitute this back in
y-3 = -2(x^2 +2x+1)
Distribute
y-3 = -2x^2 -4x -2
Add 3 to each side
y-3+3 = -2x^2 -4x -2+3
y = -2x^2 -4x +1
97-54=43
97 and b are the same angle so therefore you can subtract 97-54=43
You will need to know how much each lunch cost
so
9.40 <span>÷ 4 = 2.35
so each lunch cost 2.35 dollars
now we need to find out how much it will cost for 10 lunches
10 x 2.35 = 23.5
so for 10 lunches it will cost 23.5</span>
