Find an equation for the inverse of the following relation.<br><br> y=12x-3
vovikov84 [41]
<h3>Answer:</h3>

<em>Your answer would be y=x+3/12</em>

<h3>Step-by-step explanation:</h3>

Firstly, you'll switch sides of the equation.

<em>y=12x+3 ---> x=12y-3</em>

Next, add 3 to both sides.

<em>x=12y-3 ---> 12y-3+3=x+3</em>

Simplify it.

<em>12y-3+3=x+3 ---> 12y=x+3</em>

Then, divide both sides by 12.

<em>12y=x+3 ---> 12y/12 = x/12 + 3/12</em>

Simplify once more.

12y/12 = x/12 + 3/12 --- y= x+3/12

<u>y=x+3/12 would be your answer.</u>

Rachel's aunt gave her $85 to spend on
Orlov [11]

The amount Rachel has left of the amount given to her by her aunt after she makes the purchases is  $22.15.

<h3>How much does Rachel have left?</h3>

In order to determine the amount she would have left, determine the total value of the purchases and subtract it from the amount she was given.

Total value of the purchases = (4 x 0.85) + 45.50 + (5 x 2.79) = $62.85

Change =  $85 - $62.85 = $22.15
