On Saturday, the feature sold 40 tickets to the late show. On Sunday, 60 tickets were sold. Find the percent of change and label it as an increase or decrease.

150%

Step-by-step explanation:

60/40=x/100

=> x*40=100*60

=> x=100*60/40

=> x=150%

please mark as brainliest, l need it

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)
