Answer:
A
Step-by-step explanation:
First 4 sets of (x, y) show that when x increases 2, y increases 3. It seems the relationship is linear. But last 2 set show that x increases 1, y increases 3. So the relation is NOT linear
1a) no it would be 54
1b) yes
1c) yes
1d) no it would be 40
1e) yes
hope this helped
(0.1x-22)+(0.3x-54)=90
First combine like terms
0.4x - 76 = 90
Now add 76 on both sides
0.4x = 166
Divide by 0.4 on each side to isolate x
X= 415
