The equation can be made by:

Letting x be the price of each tshirt sold

Y be the cost of washing cars

So the equation 1:

292.50 = 15x + 12y

Then the equation 2 is for this week:

<span>747.50 = 45x + 10y</span>

You have been asked to find the inverse of f (x) = 3+Vx - 1. What would your
Paha777 [63]

Answer:

Add 1 to both sides of the equation.

Subtract 3 from both sides of the equation.

Step-by-step explanation:

The inverse of a function refers to that function that tends to undo another function.

If we intend to find the inverse of the function, f(x) = 3+ V2 - 1, we have to first add 1 to both sides of the equation and subsequently subtract 3 from both sides of the equation before taking the square root of both sides to obtain the inverse function.

Step-by-step explanation:

I hope this helps you :)
