AB = BC
3x-4=5x-10
-4=2x-10
6=2x
3=x
AB = 3x-4
AB = 3 (3)-4
AB = 9-4
AB =5
Therefore, AB is 5.
BC = 5x-10
BC = 5(3)-10
BC = 15-10
BC= 5
Multiply both by -1: 113.75-112=1.75
multiply answer by -1: -1.75
I'm pretty sure the answer is D observational study.
I have attached an image explaining how to solve this problem.
(“m” means slope)
Answer:
-18
Step-by-step explanation:
The answer is -18 because a negative plus a positive is always a negative.
