Answer:

C or D

Step-by-step explanation:

I'm taking this same thing, not sure if it's c or d. The thing that I'm puzzled about is what the difference between the white dot and the black dot is.

Option D shows the solid dot along with  [tex]x\leq 7[/tex] so our answer is

Option D.

The given inequality is  2x + 1  [tex]\leq[/tex]  15.

We have to see which of the given option shows the solution and graph to this inequality.

What are a solid dot and an open dot?

A solid dot indicated on a number line graph shows that the given number is also a possible solution, whereas an open dot indicates that the given number cannot be a solution.

We see that in the given inequality, 2x + 1 must be less than or equal to 15.

And the maximum value we can take is 7 because,

2(7) + 1

14 + 1

15

So we can take 7 and any values less than 7 i.e  [tex]x\leq 7[/tex]  to satisfy the inequality  2x + 1  [tex]\leq[/tex]  15.

We see that Option D gives us  [tex]x\leq 7[/tex] along with the solid dot.

Hence Option D is our answer.
