11. what is the y- intercept of this graph? b. what does the y-intercept represent
12.your friend incorrectly makes this graph as an example of a line with a y-intercept of 3
explain your friends possible error.
(graph 2) draw a line on the graph that does represent a y-intercept of 3.
13. (graph 3 and 4) what is the y-intercept of each graph?

step-by-step explanation:

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.

hint: which coefficient is a multiple of 360°?
