Answer:
Hello,
If f(x)=5x-13, then f^-1(x)= ![\frac{1}{5x-13}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B5x-13%7D)
have good day
Step-by-step explanation:
General equation of slope intercept form is y=mx+c. m=-5, b= - 7 = c. Plugging these values in general equation you'll get, y= - 5x - 7. Option C is the correct answer.
$2.40/34= 0.070588235294118 is the answer I believe
Answer:
-2x +4 = 20
Step-by-step explanation:
given
![- 2x + 4 = 20](https://tex.z-dn.net/?f=%20-%202x%20%2B%204%20%3D%2020)
by making x the subject, you need to subtract 4 from 20
thus
![- 2x = 20 - 4](https://tex.z-dn.net/?f=%20-%202x%20%3D%2020%20-%204)
![- 2x = 16](https://tex.z-dn.net/?f=%20-%202x%20%3D%2016)
and also you need to divide through by -2
![\frac{ - 2x}{2} = \frac{16}{ - 2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B%20-%202x%7D%7B2%7D%20%20%3D%20%20%5Cfrac%7B16%7D%7B%20-%202%7D%20)
![x = - 8](https://tex.z-dn.net/?f=x%20%3D%20%20-%208)
