#4 which input is not allowed?

x = -2

Step-by-step explanation:

Since we cannot divide by 0, the value of x which results in a denominator that is 0 is a value excluded from the domain;

This value can be found by setting the denominator equal to 0;

In this case, the denominator is -5x - 10 so we construct the following equation and solve;

-5x - 10 = 0

5x = -10

x = -2

Step-by-step explanation:

-5x-10≠ 0

-5x≠ 10

x≠ -2

-2 is not allowed i.e option A

i can

step-by-step explanation:

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
