Answer:
t=-148+1/1.5740740740741
Step-by-step explanation:
(t)=-0.32+2.7t+253
We move all terms to the left:
(t)-(-0.32+2.7t+253)=0
We add all the numbers together, and all the variables
t-(2.7t+252.68)=0
We get rid of parentheses
t-2.7t-252.68=0
We add all the numbers together, and all the variables
-1.7t-252.68=0
We move all terms containing t to the left, all other terms to the right
-1.7t=252.68
t=252.68/-1.7
t=-148+1/1.5740740740741
X = t +4
y = t^2
Rewrite the first equation:
x = t+4
Subtract 4 from each side:
t = x-4
Replace t in the 2nd equation with the rewritten equation:
y = x-4^2
Rewrite x-4^2 as (x-4)(x-4)
Use FOIL to get y = x^2-8x+16
The answer is D.
