What’s 2/3x1 1/7x3/8 thank you

Given: x + y = 6. if xe (-15, -6, -1), then which of the following sets of ordered pairs are solutions? © {(-15, -21), (-6, -12), (-1, -7)} [(-15, 21), (-6, , 7)} {(-15, 21), (-6, 12), (-1, -7)}

What value of x is in the solution set of 4x - 12 s 16 + 8x? -10 -9 -8 -7

For the following geometric sequence, find the recursive formula. {-80, 20, -5, } i need : ')
