Question

Determine whether the given numbers are solutions of the inequality.

1, -17, -14, -3
y-9>2y-2

Explanation / Answer

y - 9 > 2y -2 when y = 1, -8 > 0, this is not true when y = -17, -26 > -36, this is true. this is one of the solutions when y = -14, -23 > -30, this is true. this is one of the solutions when y = -3, -12 > -8, this is not true or you can calculate the value of y when y-9 = 2y-2 y-9 = 2y -2 y = -7 when y = -6, y-9 = -15 where 2y -2 =-14. so y-9 < 2y-2 when y = -8, y-9 = -17 where 2y-2 = -18, so y-9 > 2y-2 so any value of y < -7 will be true for y-9>2y-2 inequality
