A set of numbers is shown below: {0, 0.6, 2, 4, 6} Which of the following shows all the numbers from the set that make the inequality 2x + 3 ≥ 7 true? (1 point) {4, 6} {0, 0.6, 2} {0, 0.6} {2, 4, 6}

OpenStudy (zzr0ck3r):

take the numbers in the set and plug them in to \(2x+3\ge 7\) and if it is true, then that number will be in the solution set.

OpenStudy (faiqraees):

How about if you show us your working?

OpenStudy (zzr0ck3r):

if you plug in 0 is it true?

OpenStudy (acespeedfighter):

wait i messed up one sec

OpenStudy (faiqraees):

A little hint on what he meant Plugging means equate x to that value Like if in a set there is a 1 then x = 1 2(1)+3≥7 6≥7 which is not true

OpenStudy (acespeedfighter):

its ot true 2,1+3=6

OpenStudy (acespeedfighter):

not*

OpenStudy (faiqraees):

Yes that's what I said. Try figuring out numbers for which inequality is true

OpenStudy (acespeedfighter):

I wanna say "A" but im not sure

OpenStudy (faiqraees):

Yes very good. 4 and 6 both satisfies the inequality. But there is just one number left

OpenStudy (acespeedfighter):

oh ok so it would be D wasnt checking myself

OpenStudy (faiqraees):

Yes perfect
