Answer:
Graph A
Step-by-step explanation:
Based on the inequality shown, you know that the graphed line needs to be both solid and must be shaded above. This is because of the equal to or greater than sign that points toward the y. So, from that you can cancel out b and c because neither are shaded above the line. Then, you can further cancel out d because it has a dashed and not solid line.

Answer:
Solve one of the following equations for x or y and then substitute the answer to that equation into the second equation.
Step-by-step explanation:
Given the system of equations:


You could solve either one of the given equations but for this question we will solve the first equation.

Solve for x
Subtract y

Now substitute the answer for the first equation into the second equation.
Hope this helps.
First you subtract 5 from both sides which leaves you with the equation -2p=6. After that you divide 6 by -2 which gives you p=-3
