What is the reflection image of p(0, 0) after two reflections, first across x = -3 and then across y = 4? (-8, -6) (4, -6) (4, -3) (-6, 8)

(-6,8)

Step-by-step explanation:

Plot the point P(0,0) and draw the vertical line x=-3.

If point P is reflected across this vertical line, then the image point B has coordinates (-6,0).

Draw horizontal line y=4. If point B is reflected across this horizontal line, then the image point C has coordinates (-6,8) (see attached diagram for details).

for me what is finding a good play list and going out because i can not lay down and relax so i usually go to a coffee shop. i also use the gum trick and this actually works. another advice is highlighting subjects it really does me remember certain things

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.
