The answer is D. y = 1/2(x+2)^2 -3
Step-by-step explanation:
I just put each answer choice into a graphing calculator and chose the one that was equivalent, D. came out to be right
A 0 because you can not subtract 2-5 or the rest
PERIMETER = 2 (LENGTH + WIDTH)
PERIMETER = 2 LENGTH + 2 WIDTH
Given: Length 5 inches
P = 2(5 in) + 2w
P = 10 in + 2w
Perimeter is dependent in both length and width. Changes in any length of width will automatically change perimeter.
For find width using the perimeter formula:
P = 10 + 2w
P - 10 = 2w
(P-10)/2 = w
P/2 - 5 = w
w = P/2 - 5
If the perimeter and length is given, you can use the derived formula to solve for width.
I’m thinking 9 if you add both equations together then you’ll have 2x+x and y-y=5+4
3x=9
If you wanted to go further then it would be x=3 but for this I’d say the answer is 9
