Answer:
14.)x=7
15.)x=252
16.)x=4
17.)x=3/4
18.) [in the picture]
(5,20)
Step-by-step explanation:
Because 3x+2(4x)=55 is then 11x=55, then divide the both by 11 to get x=5
The substitute y=4(5) because of x the get y=20
-3/2
Remeber, to find slope we use this formula:
y - y all over x - x, or (y-y) / (x-x)
(6-9) / (5-3)
-3 / 2
= -3/2
