5x +2(x+20)+10+5x+20+3(x+10)=770. solve for x

Step-by-step explanation:

calculate those with x values

15x + 100 = 770

...then collect like terms

15x = 770-100

and divide both sides by 15

x = 670

15.

x = 44⅔

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.
