Question

I REALLY NEED HELP PLEASE

Answer 1

Answer:

10

Step-by-step explanation:

given

$\frac{s + ( - 7)}{ - 1}$

we first need to simplify the expression before we find it's value when s=-3

positive times negative=negative

so the equation becomes

$\frac{s - 7}{ - 1}$

substituting s=-3 into the equation.

$\frac{ - 3 - 7}{ - 1}$

=

$\frac{ - 10}{ - 1}$

=the negatives cancel out leaving

$= 10$
