Answer:
-7/13
Step-by-step explanation:
(1 + 7x) - 6 * (-7 - x) = 36 Distribute the 6 into (-7 - x)
1 + 7x + 42 + 6x = 36 Combine like terms (1 + 42) & (7x + 6x)
43 + 13x = 36 Subtract 43 from both sides
13x = -7 Divide by 13
x = -7/13

Step-by-step explanation:
Hi there Mary Dominguez, So what a vertical line test down is to find out if a particular graph is a function or not. What you do is take a vertical strait line and move it right to left or left to right, depending on your preference, along the X axis. The reason this works is a function can not have an x that has 2 different y values. If we use the vertical line test on a graph with say a graph that has (2,3) and (2,4) we can use the vertical line test and see that the line hits 2 points at once which means its not a function :)
