Please help!! <br><br><br> Find the inverse of y=7x-10. Is the inverse a function?
kolezko [41]

Answer: f^{-1} (x) = \frac{x+10}{7}

Step-by-step explanation:

To find the inverse , all we need do is to make x the subject of the formula.

y = 7x - 10

Add 10 to both sides

y + 10 = 7x

divide both sides by 7

Therefore:

x = y + 10 / 7 , that is

f^{-1} (x) = \frac{x+10}{7}

<u>Let's take this problem step-by-step:</u>

 

<u>First let's set up the equation for the cost for one week of renting the car</u>

  • agency charges $230 per week

              charge = 230

  • agency charges $0.25 per mile (<em>lets set the number of miles as 'x')</em>

<em>               </em>charge = 230 + 0.25x

<u>The total cost was 415</u>, <em>therefore:</em>

             415 =230 + 0.25x\\185 = 0.25x\\x = 740

Therefore, you traveled 740 miles

<u>Answer: 740 miles</u>

<u></u>

Hope that helps!
