Answer:
c. 120 units^3
Step-by-step explanation:
L x W x H = <em>V</em>
3 x 4 / 2 = 6
6 x 20 = 120
Use the linear slope formula to solve for m:
m=(y2-y1)/(x2-x1)
using the points (-1,1) and (1,5) you can find the slope for the first interval:
m=(5-1)/(1-(-1))
m=4/2
m=2
you can double check by using the same formula on the second interval, which is (1,5) to (3,9).
m=(9-5)/(3-1)
m=4/2
m=2
therefore, the rate of change is 2.
Take away 1 from either side so the equation becomes 63=3x then divide both sides by 3 so it becomes 21=x which is your answer (option A)
70 is a composite number because it can be divided by numbers other than one and itself.
