The excluded values of a rational expression are –3, 0, and 8. which of the following could be this expression?
x+2/x^3-5x^2-24x
x+2/x^2-5x-24
x^3-5x^2-24x
x^2-5x-24/x+2

has denominator

Option 1 is correct.

Step-by-step explanation:

Given: The excluded values of a rational expression are –3, 0, and 8

The excluded value of any function is vertical asymptotes.

We get vertical asymptotes when denominator becomes 0.

If we find a function of excluded value it must we equivalent to denominator of function.

Function of excluded value, (x+3)(x-0)(x-8)

Now we will simplify it

Now, we will check each option those has denominator

Hence, Option 1 has denominator

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9

step-by-step explanation:

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
