Make a conjecture about the product of an even and an odd number based on the following pattern: 2 = 2 x 1
6 = 3 x 2
30 = 5 x 6
56 = 7 x 8
90 = 9 x 10
and so on.
The product of an even and an odd number is equal to the square of the odd factor.
The product of an even and an odd number is equal to the sum of the factors.
The product of an even and an odd number is an even number.
The product of an even and an odd number is a prime number.

Which equation can be used to solve for the unknown number? seven less than a number is thirteen. n-7=13 7-n=13 n+7=13 n+13=7

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.
