PLEASE HELP Julie created two 4 sided fair die. On one die, she used the letters that spell MATH and wrote one letter on each side. On the second die, she used the letters that spell STAT and wrote one letter on each side.

Julie is going to roll both of her die at the same time.

Julie made a list of the unique two-letter combinations that she can get when she rolls both die. The order of the two letters does
not matter. For example, AM and MA is the same combination

How many unique two letter combinations are there?

A. 12
B. 16
C. 24
D. 11

Arrange the steps to solve this system of linear equations in the correct sequence. x + y = -2 2x – 3y = -9 tiles subtract 3x + 3y = -6 (obtained in step 1) from 2x – 3y = -9 (given) to solve for x. substitute the value of x in the first equation (x + y = -2) to get y = 1. the solution for the system of equations is (-3, 1). x = -15 the solution for the system of equations is (-15, 13). add 3x + 3y = -6 (obtained in step 1) to 2x – 3y = -9 (given), and solve for x. x = -3 substitute the value of x in the first equation (x + y = -2) to get y = 13. multiply the first equation by 3: 3(x + y) = 3(-2) 3x + 3y = -6.
