A set of numbers is shown below:

{0, 0.8, 1, 3, 6}

Which of the following shows all the numbers from the set that make the inequality 7x + 1 ≥ 8 true?

Respuesta :

1, 3, and 6 makes the inequality true. 0 and 0.8 as x will give a value less than 8.

Answer:

1, 3 and 6 makes the inequality true

Step-by-step explanation:

find the numbers that make the inequality 7x + 1 ≥ 8 true

7x + 1 ≥ 8

Lets check with each number and decide

LEts plug in x=0

7(0) + 1 ≥ 8

1 ≥ 8  is false

LEts plug in x=0.8

7(0.8) + 1 ≥ 8

6.6 ≥ 8  is false

LEts plug in x=1

7(1) + 1 ≥ 8

8 ≥ 8  is true

LEts plug in x=3

7(3) + 1 ≥ 8

22 ≥ 8  is true

LEts plug in x=6

7(6) + 1 ≥ 8

43 ≥ 8  is true
