Aclothing store used the sign show below to advertise a discount on shirts: discount: buy two shirts get 50% off third shirt ky wants to buy three shirts, which were originally priced $49.96 each. the store will discount the price of the third shirt and then apply a 7.1% tax to the total cost of all three shirts. including the tax, what will the mean cost of each shirt? a)$41.99 b)$42.70 c)$44.59 d)$45.18

d is the correct answer

step-by-step explanation:

x= 8 because 3x = 3 * 8, and 3*8 = 24

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
