R = x(A+B)
distribute
R=Ax+Bx
subtract Ax from each side
R-Ax=Bx
divideby x
(R-Ax)/x =B
Choice C
The error Vincent made was that he only multiplied the left side of the inequality with 6 although he had to multiply on both sides
Step-by-step explanation:
Given inequality that the teacher wrote is:
Solving an inequality means that the variable should be isolated on left side of the inequality.
So multiplying both sides by 6
Vincent got the answer is x<-2 = > The error Vincent made was that he only multiplied the left side of the inequality with 6 although he had to multiply on both sides

The positive numbers will out rule the negative number. It's sort of like placing blocks over another set of blocks. :)
Answer:
1. y = 2x
2. y = x + 2
3. y = 2
Step-by-step explanation:
the real equation is:
y = 2x + 0 which is the same as y = 2x.
Equation for 2:
y = 1x + 2.
Equation for 3:
y = 2
Sloper: 0
y-intercept: 2
