Answer:

19

Step-by-step explanation:

add 12 to both sides to get x = 19

12 + 12 = 0 since your getting rid of the constants and 12 + 7 = 19 so x = 19

Use the opposite operation in which its formed in

For example 3x = 18

you would have to multiply 3 by x right? So the opposite operation of that is divide by 3 since you dont know the value of x so do the known value which is the number 3 once you divide 18 by 3 you get 6 so put 6 on the right side and keep the equal sign between them to get x = 19.

What is happening to this graph when the x-values are between 4 and 8?
Vilka [71]

Answer:

The correct answer is A. It is constant.

Step-by-step explanation:

When the x-values are between 4 and 8, this graph is constant.  This can be seen because the graph is a horizontal line, meaning it has zero slope.  Since the slope is zero, it is neither increasing nor decreasing, and is known as constant.

Hope this helps!
