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}

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

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
