A rectangle with a perimeter of 9 units is graphed on a coordinate grid. The square is dilated by a scale factor of 0.2 with the origin as the center of dilation. If (x, y) represents the location of any point on the original triangle, which ordered pair represents the coordinates of the corresponding point on the resulting triangle? A. (x + 0.2, y + 0.2)

B. (.2x, .2y)

C. (9x, 9y)

D. (x + 9, y +9)

The variable z is directly proportional to x, and inversely proportional to y. when x is 4 and y is 13, z has the value 1.2307692307692. what is the value of z when x= 9, and y= 20

Aretha wanted to gather data about the cost of local bowling leagues in her area. she plotted the data and determined that the average bowling league costs consist of a one-time registration fee and a monthly fee modeled by the equation y = 15x + 20. identify and interpret the y-intercept in this model. the y-intercept is 20. this is the cost per month. the y-intercept is 20. this is the cost of registration. the y-intercept is 15. this is the cost of registration. the y-intercept is 15. this is the cost per month.

The roots of the function f(x) = x2 – 2x – 3 are shown. what is the missing number?
