Answer:
6 and -8
Step-by-step explanation:
Solve:
xy = 48
x + y = -2
You can say y = -2-x = -(x+2) and then substitute that in the first:
-x(x+2) = 48
-x² -2x - 48 = 0
x² + 2x + 48 = 0
Quadratic formula can do the rest if you don't "see" the factorization.

Step-by-step explanation:
Option C is the correct answer
1. it says no more than 5 so that includes 5, so there are 5/8 probability
2.since this spinner stops on an even number (8) that means half are even and half are odd so 4/8, but you can reduce that to 1/2
3.since it says less than 3 there are only two so that ends up being 2/8 or 1/4 probability
Price of 12 pounds of trail mix = 12 x $4.20
= $50.40
Let the number of pounds of skittles and trail mix be x,
number of pounds of skittles = 12 - x
price of pounds of skittles = $16.70(12 - x)
= $200.40 - 16.7x
total amount = 10.93x
200.40 - 16.7x + 50.40 = 10.93x
250.80 = 27.63x
x = 10 (nearest whole number)
the minimum number of pounds of skittles is 10.
