Answer:
-1.25 :)
Step-by-step explanation:
I dont know exactly your answer but ill tell you how to solve add all your numbers together and then divide it by 45 (the number of numbers u have)
The factorization of A is y = (x - 8)(x + 7).
The factorization of B is y = (x + 1)(x - 4)(x - 5)
In order to find these, you must first find where each graph crosses the x-axis. In the first problem it does so at 8 and -7. In order to find the correct parenthesis for those, you need to write it out as a statement and then solve for 0.
x = 8 ---> subtract 8 from both sides
x - 8 = 0
This means we use (x - 8) in our factorization.
You then need to repeat the process until you have all the pieces. In the second problem, there will be 3 instead of 2 since it crosses the axis 3 times.
Given the quadratic equation:
Using the general solution for quadratic equations:
From the problem, we identify:
Then:
And the solution set is:
![\lbrack\frac{-5-3\sqrt{5}}{2},\frac{-5+3\sqrt{5}}{2}]](https://tex.z-dn.net/?f=%5Clbrack%5Cfrac%7B-5-3%5Csqrt%7B5%7D%7D%7B2%7D%2C%5Cfrac%7B-5%2B3%5Csqrt%7B5%7D%7D%7B2%7D%5D)
