the size of the painting is 39 inches by 51 inches.

Step-by-step explanation:

Size of the painting: A * B

Scale factor: 1/3

Size of the photo: [1/3]A * [1/3]B

[1/3]A = 13inches => A = 13inches * 3 = 39 inches

[1/3]B = 17 inches => B = 17 inces * 3 = 51 inches.

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.

the answer would be 0.54
