A local dealership provides you with statistics that show the number of each color car they sold last year along with the percentages that those sales represented relative to their inventory for that color car. For each color, how many cars did the dealership have in its inventory before they started selling them?

red: 20

white: 30

black: 25

silver: 40

other: 12

Step-by-step explanation:

To find the original number of cars per color in the inventory, divide the sold number of cars by the percent of the inventory.

red: 20 = 10/0.5

white: 30 = 21/0.7

black: 25 = 19/0.76

silver: 40 = 10/0.25

other: 12 = 4/0.33

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
