Answer: The answer would be c
Step-by-step explanation:
Step 1: Solve for b
5a+b=7
b=-5a+7
your slope would be -5a
Step 2: Make it perpendicular
The Perpendicular is gonna be the opposite
So it would be b= 1/5+7
The slopes has to be different and you don't have to worry about the "+7"

Answer:
Victor gives 28 tools to IIya.
Step-by-step explanation:
Consider the provided information
The ratio of the number of Victor’s tools to the number of Ilya’s tools is 5:2
Let V represents the Victor and I represent llya
Therefore,

It is given that Victor has 42 more tools than Ilya.

Solve the above equation.




Thus, IIya has 28 tools.
Victor has 42 more tools than Ilya. Therefore 42 + 28 = 70.
Victor has 70 tools.
We want to find the number of tools victor needs to give to IIya so that the ratio of the number of Victor's tools to the number of Ilya’s tools will be 3:4
Let Victor gives x tools to IIya. Thus,





Hence, Victor gives 28 tools to IIya.
