Given:

The inequality is

c\leq 7

Where, c is the number of cars in the parking lot.

To find:

The graph for the given inequality.

Solution:

We have,

c\leq 7

Here, the value of c can be any real number less than or equal to 7. But c is the number of cars, so c must be a non-zero integer.

Since, all the non-zero integer values less than or equal to 7 are included in the solution set, therefore, c = 0,1, 2,3,4, 5,6,7.

In the graph of the given inequality, there are close circles on  0,1, 2,3,4, 5,6,7 as shown in option D.

Therefore, the correct option is D.

-3a - 3 = -2 + 3p ˢᴼᴸᵛᴱ ᶠᴼᴿ ᴬ
skad [1K]

Hi!

-3a - 3 = -2 + 3p

-3a=3p+1

\frac{-3a}{3}=\frac{3p+1}{-3}

Answer------>a=-p+\frac{-1}{3}

Explanation: <u><em>First you had to add by 3 from both sides. It gave us -3a=3p+1. Then divide into -3 from both sides. It gave us -3a/-3=3p+1/-3, or a=-p+-1/3 is the right answer. Hope this helps! And thank you for posting  your question at here on Brainly. And have a great day. -Charlie</em></u>
