Answer:
The answer is C.
Step-by-step explanation:
I just did the test and the answer was C
Since you have exponents this is what you end up getting.
I only used the calculator for the multiplying. (Also I used * for multiplying)
(12x^4+5x^3+3x^2-5)/(x+1)
(12x*x*x*x+5x*x*x+3x*x-5)/(x+1)
(12+5+3-5)/(x+1)
(15)/(x+1)
You divide.
You get 15.
Now you add up the x's.
15x^9 plus another x because of the one in the other parentheses.
Answer: 15x^10
Answer:
It takes 2.4 hours to travel 480 miles.
Step-by-step explanation:
From the graph race car is moving at 100 miles in 0.5 hours. So, in 1 hour, car could travel 2*100 =200 miles per hour.
So, we can set up equation as
y= 200x.
Plug in y as 480 then solve for x.
480 =200x
Divide both sides by 200
2.4=x
So, it would take 2.4 hours.
The scale factor can be found by setting a proportion.
16/10 = 8/5
