What is the degree of the monomial? -9 a 1 b -10 c -8 d 0

recall that the degree of a polynomial or a monomial in this cases, comes from the term with the highest degree.

now, this is a monomial, and is just one term, its degree will come from the sum of all its variables' exponents, so we can see this one as,

recall that anything raised to 0 is 1, except for 0 itself, so -9x⁰ is really -9*1 or -9.

where are the options?

step-by-step explanation:

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
