If you are solving a system of equations by graphing it, the point of intersection makes both equations true! C:
Surface area of cylinder = 2πrh + 2πr^2
SA for cylinder A = 2π x 2 x 2 + 2π x (2)^2 = 8π + 8π = 16π
SA for cylinder B = 2π x 2 x 4 + 2π x (2)^2 = 16π + 8π = 24π
Answer:24 + 24 = 48
you multiply the lenth and with for each of the rectangles
(2,-2)(5,7)
7-(-2)= 9
5-2= 3
9/3= 3
slope = 3
(you could also calculate the slope by just counting up how many units it goes up/down when you pick a point from the x-axis and move left/right. basically counting the rise over run)
Answer:
The first one and the last one. A and D.
Step-by-step explanation:
A linear equation is and equation where the line is going up on a graph. In order for that to happen, y must always be bigger than x. The first and last chart all the way to the right is the only one that has that trait. :)
