Which best describes the graph of the function f(x) = -5x ?

This is a simple slope intercept form equation: y=ax+b

Where a is the slope and b is the y-intercept, but in this problem the y-intercept is 0 so it is no shown.

The line on the graph would be negative (downward) because of the negative and would be going down by a slope of -5.

  -down 5 over 1 ( rise over run )

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.
