Answer:
The system of equations is
![x+y=15](https://tex.z-dn.net/?f=x%2By%3D15)
Step-by-step explanation:
Let
x------> the number of videos of new releases
y-----> the number of classics videos
we know that
------> equation A
------> equation B
Using a graphing tool
Solve the system of equations
Remember that the solution of the system of equations is the intersection point both graphs
The intersection point is ![(4,11)](https://tex.z-dn.net/?f=%284%2C11%29)
see the attached figure
therefore
the number of videos of new releases is ![4](https://tex.z-dn.net/?f=4)
the number of classics videos is ![11](https://tex.z-dn.net/?f=11)
Answer:
11 inches by 11 inches
Step-by-step explanation:
The dimensions of the original photo were 11 inches by 11 inches.
We are informed that the area of the reduced photo is 64 square inches and that In the equation (x – 3)^2 = 64, x represents the side measure of the original photo.
In order to solve for x, we shall first take square roots on both sides of the equation;
The square root of (x – 3)^2 is simply (x - 3).
The square root of 64 is ±8 but we ignore -8 since the dimensions of any figure must be positive.
Therefore, we have the following equation;
x - 3 = 8
x = 8 + 3
x = 11
