Answer:
x = -7
Step-by-step explanation:
3(x+7) = -15
First, distributive property. Therefore, you multiply 3 with x and 7
3x + 21 = -15
Then, you need x to be isolated. So you will have to -21 from +21 on both sides of the equation to make it balanced.
3x + 21 = -15
<u> -21 -21</u> (21 will be canceled from the left side of the equation)
3x = -35
Lastly, you need to divide 3 from both sides of the equation, as 3 is multiplied with x.
<u>3x</u> = <u>-35</u>
3 3 (3 will be canceled from the left side of the equation)
<em><u>x = -7</u></em>
In a rational function, holes are located where f(x) is undefined(the denominator is 0), but the undefined points can be factored out. In f(x), when x is 4 or -3, f(x) is undefined. But, x+3 can be factored out, so it is a hole. The hole is located at (-3,-1/7)
