Reflect the figure over the line y= -x -2
pls help no tutors know the answer!!​

You'll have a quadrilateral with the following points

A diagram is posted below.

===================================================

Explanation:

The given quadrilateral has four unmarked points. I'll add the point labels A,B,C,D such that

I started at the lower right corner and worked my way clockwise.

----------------

Let's shift the line y = x-2 up two units so that it moves to y = x

We'll need to shift every point of the quadrilateral up two units as well.

So we have these new point locations after the shifting has occurred.

----------------

Now we need to reflect over the diagonal line. The rule to reflect over the line y = x is as simple as swapping the x and y coordinates.

So we can say

A point like (-3, 5) moves to (5, -3)

We have these new locations

----------------

The last thing to do is to shift everything down 2 units. This is to undo the first step we did when we shifted everything up by 2 units.

Doing this leads to these locations

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.
