Answer:
y = x^2 +8x +16
Step-by-step explanation:
t can be written in terms of x, then substituted into the equation for y.
x = t -4
x + 4 = t
y = t^2 = (x +4)^2
y = x^2 +8x +16
Answer: 27 x 3 − 270 x 2 + 900 x − 1000
Step-by-step explanation: Expand the expression.
Answer:
The accumulated amount would be $4,353.56
Step-by-step explanation:
r= 0.08
A= 3, 200(1+0.08)^4
= 3,200(1.08)^4
= $4,353.56
First you plug in the known variables. So 192 for x and 3 for t. Lastly you get y = 192(3)
Jason's error was that he multiplied by 2 instead of dividing. It should be m=2.
