How do i even do number 14 and what is the answer?

Start by solving the inequality for r.  You do this like you would solve any other two step equation:

*Subtract 7 from both sides*

r/4≥-1

*Multiply both sides by 4*

r≥-4

To graph this, you will start at -4.  You need to determine whether you will draw an open or a closed circle at -4.  An closed circle is drawn when the inequality is greater than or equal to (it includes the value at the circle).

Draw a closed circle at -4.

Next, you need to determine which way to draw the arrow.  If it is greater than, you draw an arrow to the right; if it is less than, the arrow is to the left.

Draw an arrow to the right.

Hope this helps!

the correct answers i think are b. and d.

give me brainliest if it is correct!
