A hairdresser receives a discount on each comb purchased. The original price of each comb is x dollars. The hairdresser purchases 12 combs for a total of (12x-24) dollars. By how much is each comb discounted?

2 dollars

Step-by-step explanation:

The original price of the comb is x dollars.

The hairdresser purchases 12 combs for a (12x -24)dollars

To get the amount charged per comb, divide the price for 12 combs by 12

The amount charged for each comb will be =

=x-2

amount per comb is x-2 dollars.

since the original price of each comb is x dollars, it means 2 dollars was discounted from each comb

y = - 6

step-by-step explanation:

given the point (- 2, y) lies on the graph then it is a solution of it's equation.

substitute x = - 2 into the equation for value of y

y = 3(- 2) = 3 × - 2 = - 6

the point on the graph is (- 2, 6)

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
