It is not linear because x is raised to the second power. Therefore it is not straight and would be kindof like a rainbow cut in half on the graph..
Answer:
13
Step-by-step explanation:
We need to write our answer in exponential form. Ask yourself the question, "What times itself 3 times will give you 2197?" Your answer is 
. This will go inside of your cube root. You now have ![\sqrt[3]{13^{3} }](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B13%5E%7B3%7D%20%7D)
. Since there's a power of 3 and a cube root, those cancel each other out, and your answer is 13.
x= morning
y = afternoon
x + y = 10
x=10-y
5x + 6y =57
5(10-y) +6y =57
50-5y +6y =57
y=7
x=10-7 =3
check 3*5 = 15, 7*6 = 42, 42 + 15 = 57
