Which of the following sets shows all the numbers from the set {0, 0.5, 1, 2.5, 3} that make the inequality 2a + 3 ≥ 8 true? (4 points)


{2.5, 3}

{1, 2.5, 3}

{0, 0.5, 1}

{0.5, 1}

Answer 1

For both of these plug in your options into the equations and see what makes a true statement.

Answer 2

hmm....

Answer 3

#1
3(4) + 4(2) + 6 = 26
Your first option is
x = 4, y = 2

So take 4 and 2 and sub them in for the variables (be sure to put them in the right place)
If its true you should get 26=26 if it's not you'll get any number=26
So on an so forth if those don't work try your 2nd option.

#2
2a + 3 ≥ 8
First option
{2.5, 3}

Plug those in for a and see if they make a true statement
2(2.5)+ 3 ≥ 8

2(3) + 3 ≥ 8
If they do good if they don't try the 2nd option etc

Answer 4

1. C
2. im not to sure but i think its B or A

Answer 5

1)
C: 3(4) + 4(3) + 6 = 26
12+12+6=26
30=26
C is incorrect.

2) Don't guess actually try.
