Answer:
1.7r
Step-by-step explanation:
2(5x)2(-7)=2x+10
2(5x)= 10x
2(-7)=-14
10x-14=2x+10
Solve:
10x-2x=8x
8x-14=10
14+10=24
8x=24
24/8=3
X=3
NO they are not proportional
3/7 = .4285714
6/9 = .66666
If they’re about coordinates, the first one is true and the next two are not.
But if it’s not about coordinating they’re all true.
