TIMED PLZ HELP A. y = 4x + 5
B. y = 1/4 - 2
Slope =
Slope =
y-intercept
y-intercept
11

Step-by-step explanation:

y-intercept form: y =mx +b

Here m is slope and b is y-intercept

A) y = 4x + 5

Slope = 4

y-intercept = 5

B) y = 1/4x -2

Slope = 1/4

y-intercept = -2

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.
