PL answer these questions How do you figure out if a relation is a function?
How do you find function tables with problems such as y=4x- 1 and y= 1/2 x +5?
How do you find Functions representing values in a table?
How do you find Slopes in Coordinate planes?

These aren't real questions on a paper, but I need these answers to help me on something.

for the last question, there is a slope calculator on the internet that could help with that

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.
