Which equation is best represented by this graph?

the answer is d, y-2=5/7(x-7) (I used trial and error btw)

Step-by-step explanation:

1st step is to simplify this equation a demonstration would look like this,

y-2=5/7(x-7)

y-2=5/7x-5 distribute 5/7 into all the numbers in parenthesis

y-2=5/7x-5

+2. +2-add 2 on both sides

y=5/7x-3-thats is it, solved fully!

2nd step is to check your answer and you can do this by is acknowledging that the y-intercept is -3 and then looking on the graph's y axis and plotting the y intercept on the graph(-3) and from that negative 3 you must apply the slope, you do so by, from -3 go up 5 units and 7 units across and make a line through that slope and y intercept and you will see it is identical to d

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11 -1> 1 -1+ a

-12 > a

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.
