6% purchased model and 26% model b. Because you add up the all of the people who were and weren’t happy for both so it was 35 people in total.
So for a you divide 2 by 35 and then multiply that by 100 and then round and you get 6%
For b you divide 9 by 35 mult. By 100 and then round you get 26%
Answer:
5. A) two solutions
6. one solution
Step-by-step explanation:
5. A graph shows the curve has two x-intercepts, so two solutions. You can also figure this by looking at the discriminant:
b^2 -4ac = (7)^2 -4(-4)(8) . . . . a positive number
When the discriminant is positive, there are two real solutions.

6. The equation factors as ...
0 = 3(x +3)^2
This will have one real solution at x=-3.
The uppercase delta Δ means "change in" so for example: Δx = difference between two x values.
The lowercase delta which Brainly does not have, looks like a squiggly lowercase d. It generally means "very small change in".
Simplified would be 4xy + 3x^2 + 6x
Answer:
(2,3)
Step-by-step explanation:
The solution to a linear system is always where both of the lines intersect.
