Subtract 9.25 by 2.50, then subtract 6.75 by 2.25
For 4r - 9>7 it is <span>r>4

Y = -1/3x + 2
Explain: subtract 3x from 18, which will get you -3x + 18.
Next, get 9y and divide it by everything so it’ll look like 9y = -3x + 18
-——-————
9y
and you’ll get y = -1/3x + 2

Answer:
50 Minutes.
Step-by-step explanation:
The function c approximates the total number of calls made after m minutes since the start of the phone tree.
![c(m)=\frac{2}{3}\times (3^{\frac{m}{10}}-1)](https://tex.z-dn.net/?f=c%28m%29%3D%5Cfrac%7B2%7D%7B3%7D%5Ctimes%20%283%5E%7B%5Cfrac%7Bm%7D%7B10%7D%7D-1%29)
We need to find the number of minutes after which the total number of calls will 363.
Substitute c(m)=363 in the given function.
![363=\frac{2}{3}\times (3^{\frac{m}{10}}-1)](https://tex.z-dn.net/?f=363%3D%5Cfrac%7B2%7D%7B3%7D%5Ctimes%20%283%5E%7B%5Cfrac%7Bm%7D%7B10%7D%7D-1%29)
Multiply 3/2 both sides.
![363\times \frac{3}{2}=(3^{\frac{m}{10}}-1)](https://tex.z-dn.net/?f=363%5Ctimes%20%5Cfrac%7B3%7D%7B2%7D%3D%283%5E%7B%5Cfrac%7Bm%7D%7B10%7D%7D-1%29)
![242=3^{\frac{m}{10}}-1](https://tex.z-dn.net/?f=242%3D3%5E%7B%5Cfrac%7Bm%7D%7B10%7D%7D-1)
Add 1 on both sides.
![243=3^{\frac{m}{10}}](https://tex.z-dn.net/?f=243%3D3%5E%7B%5Cfrac%7Bm%7D%7B10%7D%7D)
![3^5=3^{\frac{m}{10}}](https://tex.z-dn.net/?f=3%5E5%3D3%5E%7B%5Cfrac%7Bm%7D%7B10%7D%7D)
On comparing both sides we get
![5=\frac{m}{10}](https://tex.z-dn.net/?f=5%3D%5Cfrac%7Bm%7D%7B10%7D)
Multiply both sides by 10.
![50=m](https://tex.z-dn.net/?f=50%3Dm)
Therefore, the total number of calls will 363 after 50 minutes since the start of the phone tree.
