Jason had $32. He spent all the money on buying 4 CDs for $x each and 2 magazines for $y each. If Jason would have bought 5 CDs

and 2 magazines, he would have run short of $4.
A student concluded that the price of each CD is $5 and the price of each magazine is $6. Which statement best justifies whether the student's conclusion is correct or incorrect? A. The student's conclusion is incorrect because the solution to the system of equations 4x + 2y = 4 and 5x + 2y = 36 is (9, 4).

B. The student's conclusion is incorrect because the solution to the system of equations 4x + 2y = 32 and 5x + 2y = 36 is (4, 8).

C. The student's conclusion is correct because the solution to the system of equations 4x + 2y = 4 and 5x + 2y = 36 is (5, 6).

D. The student's conclusion is correct because the solution to the system of equations 4x + 2y = 32 and 5x + 2y = 36 is (5, 6).

. The student's conclusion is incorrect because the solution to the system of equations 4x + 2y = 32 and 5x + 2y = 36 is (4, 8).
B is right option
4x + 2y = 32
5x + 2y = 36 subtracting
-x=-4
x=4
4(4)+2y=32
16+2y=32
2y=16
y=8
hope this helps

"Increasing" and "decreasing" are references to what the y-values do when the x-values increase.  

Attached is a copy of all four tables, marked with whether the y-values increased or decreased on each step (and it also shows how much that increase or decrease was.

The only table that does this is the top right table in the attachment, which is your second table.

Answer:

13. \frac{\sqrt[5]{x^4} }{x}.

14. v = \pm3\sqrt{5}

15. 2.

Step-by-step explanation:

13. x^{1/5} * x^{-2/5}

= x^{1/5 + (-2/5)}

= x^{1/5 - 2/5}

= x^{-1/5}

= \frac{1}{x^{1/5}}

= \frac{x^{4/5}}{x^{1/5 + 4/5}}

= \frac{x^{4/5}}{x}

= \frac{\sqrt[5]{x^4} }{x}.

14. v^2 - 45 = 0

v^2 = 45

\sqrt{v^2} = \pm\sqrt{45}

\sqrt{v^2} = \pm\sqrt{3^2 * 5}

v = \pm3\sqrt{5}.

15. \sqrt[3]{2} * \sqrt[3]{4}

= \sqrt[3]{2 * 4}

= \sqrt[3]{2 * 2 * 2}

= \sqrt[3]{2 ^3}

= 2.

Hope this helps!
