Correct Answer: C. 9 Kilometers per hour </span>
Answer:
x = 2
Step-by-step explanation:
Both equations are equal to y, so they're also equal to each other. We then set them equal to each other:
x^2 - 2x + 1 = x^2 + 2x - 7
We now do algebra to isolate x. Subtract 1 from both sides.
x^2 - 2x = x^2 + 2x - 8
Subtract 2x from both sides.
x^2 - 4x = x^2 - 8
Subtract x^2 from both sides.
-4x = -8
Divide both sides by -4.
x = 2
divide total miles by total time:
60.9 / 3.5 = 17.4 miles per hour

Answer:
uh, I think it's 4.13
Step-by-step explanation:
5*sin(65)=4.13 now this seems a bit off but this was the only one that actually worked
