Answer: The slope is 0
Step-by-step explanation:
The slope is the difference between the y coordinates divided by the difference between the x coordinates.
Y: 9 - 9 = 0
x: -7-2 = -9
0/-9= 0
(5x+7) + (8x-21) = 90
13x-14 = 90
13x= 104
X=8
The angle measurements are 47, and 43
V=ca times height
1040=40 times h
H=1040 divide by 40
Height=26
If we assume the number of polo shirts have been sold is x, the number of casual shirts have been sold will be 4x.
x*18+4x*9=$1080
(18+36)x=$1080
54x=$1080
x=20
The number of casual shirts have been sold is 4*20=80
