Solve the system by substitution x=-y and 8x+3y=40

(8, - 8 )

Step-by-step explanation:

Given the 2 equations

x = - y → (1)

8x + 3y = 40 → (2)

Substitute x = - y into (2)

8(- y) + 3y = 40, that is

- 8y + 3y = 40

- 5y = 40 ( divide both sides by - 5 )

y = - 8

Substitute y = - 8 into (1)

x = - (- 8) = 8

solution is (8, - 8 )

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.
