You have $3 and earn $7.50 for each car you wash. Write an equation in two variables that represents the total amount A (in dollars) you have after washing c cars.

 is the equation.

Step-by-step explanation:

Given:

You have $3 and earn $7.50 for each car you wash.

Now, to write an equation in two variables that represents the total amount A after washing c cars.

So, the total amount be

And, the number of cars be

The amount earn of washing each car = $7.50.

The amount having = $3.

Now, to write an equation representing the total amount:

Hence, is the equation.

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
