Which functions have a vertex with a x-value of o? . select three options.
f(x) = |x|
f(x) = \x{ + 3
f(x) = 5x + 31
f(x) = [x] - 6
f(x) = 5x + 31 - 6

Step-by-step explanation:

1) f(x) = |x| has its vertex at (0, 0), so the x-value is 0.

2) Cannot figure out what you meant by  \x{ + 3.

3) f(x) = 5x + 31 has a straight line graph, no vertex.

4)   [x] - 6 does not have a vertex, or at least not a well-defined one like |x|

5)  Unsure of what you meant by 5x + 31 - 6.  Did you mean 5x + 25?  This does not have a vertex.

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.
