If G(X) = 3x+1, then G-1(1) is

0

Step-by-step explanation:

To find the inverse, or , we must switch G(x) and x, and then make G(x) as we are finding the inverse, and G(x) represents the starting equation.

The steps used here are that we firt subtracted 1 from both sides, and then divided 3 from both sides.

To find , we simply plug 1 into x in the inverse function, so our answer is

answer:

total cost for tiles and paints is $924.  

step-by-step explanation:

we have been given that a community hall is in the shape of a cuboid. the hall is 40m long 15m high and 3m wide.

the paint will be required for 4 walls and ceiling.

let us find area of walls and ceiling.

therefore, the area of walls and ceiling is 1410 square meters.

given: cost for 10 litre of paint is $10 and 10 litre paint covers 25 square meter. therefore,

therefore, the total painting cost is $564.

tiles will be required for floor. let us find the area of floor.

given: 1m squared floor tiles costs $3. so,

therefore, the total tiles cost is $360.

now let us find combined total cost of tiles and paint.

therefore, the combined total cost of tiles and paint is $924.
