Answer:
Yes, it is a function.
Step-by-step explanation:
A relation is a function if it passes the VLT (Vertical Line Test).
When graphed, it kind of looks like a combination between a "U" and "V" shape, meaning it passes the Vertical Line Test.
Basically to solve this, you set both equations equal to each other and solve because the angles are the same.
5x+7=8x-71
isolate x by adding 71 to both sides and subtracting 5x from both sides
3x= 78
divide 78 by 3
x=26
Step-by-step explanation:
5p/7-18=-43
5p/7=-43+18
5p/7=-25
5p=-25×7
5p=-175
p=-175/5
p=-35
not sure lol
