Answer:
2 groups of CDs
Step-by-step explanation:
Charmaine has 6 CDs total
6 divided by 3 = 2
You’d plug in the 0.6 for x. so you’d multiple 0.6 times 2.5 then you’d get 1.5 then you’d add 1.5 plus 5.8 and get 7.3
When you multiply the two binomials you get a quadratic function with a negative lead coefficient.
This function will fall on the left and fall on the right.
If the lead coefficient were positive the function would rise in both the left and the right.
