evaluate the inequality x + 4 < 2x -3 if x= 4 x= -2 x= 7 x=9 does each value of x make the statement true or false?
+14 how you do this is you plug the number x equals into the equation.
When x=4, the inequality looks like this: 4 + 4 < 2(4) - 3
Simplify: 8<5
So when x=4, the statement is false.
When x=-2, the inequality looks like this: -2 + 4 < 2(-2) - 3
Simplify: 2 < -7
So when x=-2, the statement is false
Do those steps over for x=7 and x=9.
