Decide whether the graphs of the two equations are perpendicular lines. Explain your answer. y = -3x -6
6y - 2x = 24

which expression represents the approximate length of bc?

step-by-step explanation:

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.

but which class are u may know that first
