Answer:
D. 4 real roots and 0 complex roots
Step-by-step explanation:
If I assume that the function you are saying is

There should be up to "4 roots," there can't be more or less than 4 total solutions. First, we need to check how many sign changes are there in this function. There are 3 positive real roots. Now lets check for negative roots.
There are is only 1 negative real root. Since we basically have 4 real roots, and the max is 4. There should be 4 real roots and 0 complex roots.
Answer:
-10y + 18 = -3 (5y - 7) + 5y
-10y + 18 = -18y + 21 + 5y
-10y + 18 = -13y + 21
Step-by-step explanation:
-10y + 18 = -3 (5y - 7) + 5y
-10y + 18 = -18y + 21 + 5y
-10y + 18 = -13y + 21
The answer is going to be 9. Hope that helped.
