Answer:
25m + 10b = 400
Step-by-step explanation:
Total amount that can be earned = $ 400
Amount earned on mowing a lawn = $ 25
Amount earned per hour on babysitting = $10
Amount earned for mowing one lawn is $ 25, so amount earned for mowing m lawns will be $ 25m
Amount earned for one hour of babysitting is $ 10, so amount earned for babysitting for b hours will be $ 10b
Total amount earned = Amount earned from mowing m lawns + Amount earned from babysitting for b hours
Using the values from above, we can set up the equation as:
400 = 25m + 10b
or
25m + 10b = 400
This equation represents the number of lawns they can mow, m, and hours they can babysit, b, to earn $400.

To find the inverse of a function we must clear the value of the variable x and finally return change.
By definition we have to:
Be a function of the form 
, the inverse of that function is given by:
Then we have the following function:
Where 
We clear x:
Returning the change we have:

Answer:
x=4 or -4
y=5
Step-by-step explanation:
2x-3=x+9
=3x=12
=x=12/3
x=4( could also be -4)
y=(4x2)-3
y=5
