Answer:
(-1, 5) and (3, -3)
Step-by-step explanation:
The solutions are all the points where the two functions intersect. Since the lines intersect at two different points, there are two solutions.
The two points at which the functions appear to intersect are (-1, 5) and (3, -3).
The factors would be (x-9)(x+4).
You can use the decomposition method to find this. I personally use the chart method so I do not necessarily know how to explain the decomp method in detail. However the idea and end goal are the same for both of them.
Try to find what multiplys to the last part of the polynomial but will add to the middle part.
To check your work/factors you can try multiplying/foiling them out again to see if you get your original polynomial.
Answer:
30%
Step-by-step explanation:
70% of 120 is 84. So take the remainder of 70 (30, as %'s go up to 100.) and that's the percent left. We can "fact check this" the other way around as well.
30% of 120 = 36.
84 + 36 = 120.
The price of the boots have changed/raised 30%.
