To determine whether a solution a set of a system of linear inequalities is right, you simply plug back into the equation to check your work. If the solution equals and is mathematically correct, then that's the answer. For Example, use the equation,
5x = 10
Let's say you got an answer of x = 4. Plug it back into the equation
5(4) ≠ 10. As you can see the answer is wrong. This shows you that the answer is wrong.
The correct answer is x = 2
You can plug in the numbers like 2=3(6) + b then rearrange for b so 2-18=b so the answer to your question is y=3x-16
Answer:
The number of hours worked per week
Step-by-step explanation:
To study this issue, one administrator was assigned to examine the relationship between the number of hours worked per week in a semester and that semester's GPA for a random sample of students.
Here the explanatory variable is - the number of hours worked per week.
An explanatory variable or also called an independent variable, is the variable that is manipulated by the researcher based on the variations in the response variable of an experimental study.

Answer:
D) {-1}
Step-by-step explanation:
A rational expression is "not defined" when its denominator is zero. Hence to find values of x that make the expression "not defined," you solve the equation ...
denominator = 0
2x +2 = 0 . . . . . . put the actual denominator into the equation
x + 1 = 0 . . . . . divide by 2
x = -1 . . . . . . . . subtract 1
The expression is "not defined" for x in the set {-1}.
