Answer:
225.5
Step-by-step explanation:
220 + (2.5% × 220) =
220 + 2.5% × 220 =
(1 + 2.5%) × 220 =
(100% + 2.5%) × 220 =
102.5% × 220 =
102.5 ÷ 100 × 220 =
102.5 × 220 ÷ 100 =
22,550 ÷ 100 =
225.5
Answer:
<u>multiply</u> the base and <u>add </u>the exponents
the answer is 3 reminder 1
So since the vertex falls onto the axis of symmetry, we can just solve for that to get the x-coordinate of both equations. The equation for the axis of symmetry is 
, with b = x coefficient and a = x^2 coefficient. Our equations can be solved as such:
y = 2x^2 − 4x + 12: 
y = 4x^2 + 8x + 3: 
In short, the vertex x-coordinate's of y = 2x^2 − 4x + 12 is 1 while the vertex's x-coordinate of y = 4x^2 + 8x + 3 is -1.
i would solve 4x-y =3 for y because the coefficient for y is 1
subtract 4x from each side
-y = -4x+3
divide by -1
y = 4x-3
