The rate of change is just the slope. it is the. hange in y du used by the change in x since we have the points (1,15) and (2,30) we have
so it is D. it is not when do you use a fraction and when a whole number. it will always be a fraction but sometimes this will reduce to a whole number.

Hello,
Answer C
x^3+3x²+5x+3=x^3+2x²+3x + x²+2x+3=x(x²+2x+3)+1(x²+2x+3)=(x²+2x+3)(x+1)
Answer:
Step-by-step explanation:
No. 1 “The printing of more
currency notes will increase inflation.”
Let t be time and r be rate, then if time varies inversely with the rate, the equation is
. If it takes 5 hours to drive a fixed distance at a rate of 80, we can sub those values in to solve for the constant of variation, k.
. Solve for k by multiplying 5 and 80 to get that k = 400. Now let's find a new time t when r is a rate of 70. We will use that k value to do this:
and find that it will take 20 hours to drive the distance at 70 mph when it takes 5 hours to drive the distance at 80 mph. Makes sense that it takes longer to drive a fixed distance when you are going slower.
