Solve -7(s+2)-12=37<br> What is s
Shkiper50 [21]

Answer:

<em>s= </em>-5.57 (rounded to the nearest hundredth)

Step-by-step explanation:

1. Multiply s and 2 by 7.

You'll get -7s-14. We'll come back to this later

2. Subtract 12 from 37.

You'll get 25

3. Add 14 to both sides so that you cancel out the -14.

The equation stands as -7s= 39

4. Divide both sides by -7 so that we leave <em>s </em>by itself.

s= -5.57142857

Help me please I’m so confused ):

The domain is all the x-values you can use with this function. When dealing with a function like this, you need to ask yourself, what would make the bottom equal to 0? Whatever those numbers are, you do NOT want them in your domain.

A fundamental rule is that you cannot divide by 0 or have 0 as a denominator.

So, you solve x^2+6x=0 to find that x=0 or x=-6 would make the denominator 0.

The domain is everything BUT those two values, because they essentially break your function.
