And herbalist has 15 oz of herbs costing $3 per ounce. How many ounces of herbs costing $2 per ounce should be mixed with these 15 oz of herbs to produce a mixture of costing $250 per ounce

i can't see the picture : /

idk

step-by-step explanation:

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
