Answer:

Step-by-step explanation:
Step 1: Given equation: 
To get u, by subtraction equality property subtract both sides of the equation by
.
Step 2: By division equality property, divide both sides of the equation by t.

Therefore,
.
So, in Emily’s physics class, she got
.
I think it's x2–1=0 because it's the only one that has -1 for origin of the ordinate

Answer:
f(x) * g(x) = -35x^3 - 59x^2 - 74x - 72
Step-by-step explanation:
If f(x) = 7x+9 ang g(x) = -5x^2 - 2x - 8, then
f(x) * g(x) will be:
(7x+9)(-5x^2 - 2x -8)
f(x) * g(x) = -35x^3 - 59x^2 - 74x - 72
