Answer:
![m=(y-b)/x](https://tex.z-dn.net/?f=m%3D%28y-b%29%2Fx)
Step-by-step explanation:
we have
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
Solve for m
That means -----> isolate the variable m
Subtract b both sides
![y-b=mx+b-b](https://tex.z-dn.net/?f=y-b%3Dmx%2Bb-b)
![y-b=mx](https://tex.z-dn.net/?f=y-b%3Dmx)
Divide by x both sides
![(y-b)/x=mx/x](https://tex.z-dn.net/?f=%28y-b%29%2Fx%3Dmx%2Fx)
![(y-b)/x=m](https://tex.z-dn.net/?f=%28y-b%29%2Fx%3Dm)
Rewrite
![m=(y-b)/x](https://tex.z-dn.net/?f=m%3D%28y-b%29%2Fx)
Answer:She placed the decimal point incorrectly when dividing. i took the test
The answer is B. 5P5 x 20P15.
This is because to make the second grade students to sit in the first row we have 5 seats and 5 students so we will permute the 5 students to those 5 seats. So 5P5.
Now we are left with 20 seats and 15 first grade students so we can simply permute those 15 students into those 20 seats. So 20P15.
Finally using the counting rule principle we will multiply both of these so 5P5 x 20P15.

Step-by-step explanation:
The discriminant is ![{b^{2}-4ac }](https://tex.z-dn.net/?f=%7Bb%5E%7B2%7D-4ac%20%7D)
1. 9² - 4(1)(20) = 81 - 80 = 1 so there are 2 solutions
2. (-9)² - 4(3)(-13) = 81 + 156 = 237, so there are 2 solutions
3. The first answer is correct
4. The third answer is correct
