Δabc is a right triangle. δa'b'c' has a hypotenuse of 10 after δabc undergoes a dilation by a factor of 2. if δabc has a short leg of 5 - x and a long leg of 2x, what is the length of the short leg of δabc?

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.
