Vertex form:
y-k=a(x-h)^2
h=-2,k=-20,y=-12 when x=0
thus;
-12+20=a(0+2)^2
8=4a
a=2
Equation:
y+20=2(x+2)^2
y+20=2(x^2+4x+4)
f(x)=2(x^2+4x+4)-20
f(x)=2x^2+8x+8-20
f(x)=2x^2+8x-20
36 divided by 2 is 18 cookies which means half the sugar, or 1 cup.
54 divided by 3 is 18, If 18 cookies need 1 cup, then 54 needs 3 cups
Answer:
-7
Step-by-step explanation:
-8 = (-1/4)(4) + b
-8 = -1 + b
b = -7
3(2m + 9) - 1 = 2
6m + 27 - 1 = 2
6m + 26 = 2
6m = 2 - 26
6m = -24
m = -4
