Which ordered pair makes both inequalities true? y < –x + 1 y > x (–3, 5) (–2, 2) (–1, –3) (0, –1) mark this and return save and exit

1) y < -x + 1
2) y > x

Subtitute the values of the x and y into inequalities

(-3; 5) → x = -3; y = 5
1) 5 < -(-3) + 1 = 3 + 1 = 4  FALSE

(-2; 2) → x = -2; y = 2
1) 2 < -(-2) + 1 = 2 + 1 = 3 TRUE
2) 2 > -2 TRUE

(-1; -3) → x = -1; y = -3
1) -3 < -(-1) + 1 = 1 + 1 = 2 TRUE
2) -3 > -1 FALSE

(0; -1) → x = 0; y = -1
1) -1 < -0 + 1 = 1 TRUE
2) -1 > 0 FALSE

(-2; 2)

So what you first want to find is the area of her garden.

You can do this with the formula length * width

In this case it would be:

36 * 22 

Which is equal to 792.

Now, you just want to find how many bags of topsoil she needs.

Since I'm assuming you cannot buy half of a bag of topsoil, she will end up buying extra topsoil, because you can't just cut a bag of topsoil in half and then take some of it, then buy that.

So to have enough, she must buy 3 bags of top soil, which would end up costing $9.
