Department stores are about to release a new makeup line, and a promotional kit will be sold for $42.75. The cost to produce the kits can be determined by the cost function, where x is the number of kits to be produced and sold: C(x) = 28.25x + 8,250.

Type the correct answer in the box.

569

Step-by-step explanation:

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.

x is greater than 5

step-by-step explanation:

2x+7 is greater than 17

    -7                           -7

2x is greater than 10

divide by 2 each side

x is greater than 5
