Answer:
6q or 6 * q
Step-by-step explanation:
As you do not know what the value of the variable q is, you are essentially changing it from word form to expression form.
"product" in math means multiply, so you are multiplying 6 with q.
6q is your answer.

Since you have y alone on one side of the equation......
Use substitution and plug in 1/2x-4 for y in the other equation.

Distribute

Combine like terms

Add 8 to both sides

Divide by 4
and 
Plug this value in for x

Simplify

Multiply everything by 8 and simplify

Divide.....

Your answers are:

Answer:
-72
Step-by-step explanation:
Positive because when I looked at the graph, the scattered plots are increasing up.
4x = 14y
y = 4/14(x)
y = 2/7(x) slope = 2/7
<span>-2x+7y=14
7y = 2x + 14
y = 2/7(x) + 2 slope = 2/7
parallel lines, slope is the same
both lines have slopes equal 2/7
