Answer:
y2 = (6x + 7)/36 + (Dx + E)e^x
Step-by-step explanation:
The method of reduction of order is applicable for second-order differential equations.
For a known solution y1 of a 2nd order differential equation, this method assumes a second solution in the form Uy1 which satisfies the said differential equation. It then assumes a reduced order for U'' (w' = U'').
The differential equation becomes easy to solve, and all that is left are integration and substitutions.

Answer:
The rate of change is or 1.75. That shows that the cost per video game is $1.75
Step-by-step explanation:
The change in y over change of x or slope can be calculated using the equation:
so take the last two points: (10, 25) and (15, 33.75).
33.75-25=8.75
15-10=5
8.75/5=<u>1.75</u><u> </u><u>(7/4)</u>
x=video games
y=total cost
Since slope is change in y (cost) per change of x (video games), the answer is:
1.75 cost per video game
