F(x)=5x-20 what value could be substituted for x to have a solution of 30

Step-by-step explanation:

equate them

5x-20 =30

5x =30+20

5x=50

divide both sides by 5

x=10

c

step-by-step explanation:

there is vertical asymptote at x = 2 and x = 0

vertical asymptote occurs at the points where the denominator is 0. so we can say that

x = 2 occurs when there is a factor (x-2) in the denominator, and

x = 0 occurs when there is a factor "x" in the denominator

thus, the denominator of the equation would have "x * (x-2)", this is option c only. that's the correct answer.
