No. 6/8=9/12
by multiplying the denominators you get the common denominator of 72
then multiply each numerator by the number of the opposite denominator
8x12=96
6x12=72
9x8=72
Therefore, 72/96=72/96
(6/8 = 9/12)
Slope = -3/2, b = 3
so
y = -3/2x + 3
x-intercept when y = 0
so
-3/2x + 3 = 0
-3/2x = -3
x = -3 *(-2/3)
x = 2

Answer:
Here you go
Step-by-step explanation:
The ratio of their perimeters is still 7:20. The poster is a rectangle shape. If the length of each side of a poster is proportional to the other by a certain ratio, the sum of the lengths of all sides is also proportional by the same ratio. You can suppose the lengths of four sides of poster A are 7a, 7b, 7c, 7d, so poster B has 20a, 20b, 20c, 20d. (7a+7b+7c+7d)/(20a+20b+20c+20d)=7(a+b+c+d)/20(a+b+c+d)=7/20.
A. That the rate does change , hope that helps !!
