We need more information. what graph?
Here's a graph.
Part A: The graph is a shaded region with one corner and two edges that goes forever. It's only located on the right side of the y axis.
Part B: It's not a solution because it's not in the graph.
Answer:
![{ \huge \star} \boxed{ \sqrt{3} \times 7 \sqrt{6}}{ \huge \star} \\ = \sqrt{3} \times 7 \times \sqrt{2 \times 3} \\ = 3 \times 7 \times \sqrt{2} \\ = \boxed{ 21 \sqrt{2}}](https://tex.z-dn.net/?f=%7B%20%5Chuge%20%5Cstar%7D%20%5Cboxed%7B%20%5Csqrt%7B3%7D%20%5Ctimes%207%20%5Csqrt%7B6%7D%7D%7B%20%5Chuge%20%5Cstar%7D%20%20%5C%5C%20%20%3D%20%20%5Csqrt%7B3%7D%20%20%5Ctimes%207%20%5Ctimes%20%20%5Csqrt%7B2%20%5Ctimes%203%7D%20%20%5C%5C%20%3D%20%203%20%5Ctimes%207%20%5Ctimes%20%20%5Csqrt%7B2%7D%20%20%5C%5C%20%3D%20%20%5Cboxed%7B%2021%20%5Csqrt%7B2%7D%7D%20)
<h3>
<u>21√2</u> is the right answer.</h3>
n has less than 75 copies
sold 12
so add the 12 back
n had less than 87 copies in the beginning of the day

Yes it’s correct. You just need to plug each of the x and y values to see if they satisfy the equation.
