To start off your going to plug in 4x into the equation. Which will turn into 5x + 4x = 36. You will add 5 and 4 since they both have an x in it. Which would leave you to 9x = 36. Only thing left to do is divide 36 by 9. Which would equal to 4 and that will be your answer. X=4

2 points 2. Which of the following graphs represents a FUNCTION? Choose ALL that apply B

inna [77]

Answer:

A, B

Step-by-step explanation:

Not C, D, E, because they show two points with the same x-coordinate but different y-coordinates.

In a function, each x is paired with just one y.

The graph of a function will never have two or more points stacked vertically.
