Which inequalities would have an open circle when graphed? Check all that apply. t Less-than-or-equal-to 25 -2.5 Less-than-or-equal-to m x > 5.4 One-half less-than x x > 0 answer is 3,4,5

The value of x in this system of equations is 1. 3x + y = 9 y = –4x + 10 substitute the value of y in the first equation: combine like terms: apply the subtraction property of equality: apply the division property of equality: 3x + (–4x + 10) = 9 –x + 10 = 9 –x = –1 x = 1 what is the value of y?
