X is equal to or greater than 3:
Plot x = 3 on the x-axis (horizontal axis). Then, beginning at x = 3, draw an arrow from there to the right.
Because there are only two things you can do with these two " family" members. 81 divided by 9 is 9. 9 times 9 is 81. Strictly speaking, there should be three in the family: 9,9 and 81 9 is the square root of 81. 81 is the 9 squared.
Step-by-step explanation:
Xm = (-3+3)/2 = 0/2 = 0
Ym = (2-2)/2 = 0/2 =0
so, the midpoint (Xm, Ym) is (0 , 0)
if the other side is 15 inches and the area is 90 square inches:
90/15 = 6
height = 6 inches (A)
