For this case, the first thing we must do is define variables.
We have then:
x: number of pens
y: number of pencils
We now write the system of inequations:
![x + y \leq 25 y \geq (x - 3) ^ 2 ](https://tex.z-dn.net/?f=x%20%2B%20y%20%20%5Cleq%20%2025%0A%0Ay%20%20%5Cgeq%20%20%28x%20-%203%29%20%5E%202%0A)
The solution to the system of inequations is given by the shaded region.
Note: see attached image.
I set it up as an equation. 1/4x = 1/7x + 3. After you solve it out, it’s 28.
Answer:
3 hours
Step-by-step explanation:
Given that:
Time taken by Kalon = 4 hours
Time taken by Marna =?
Time taken if the work together = 1 5/7 hours
Kalon's rate = 1/ time =. 1/4
Kalon + Marna = 1 ÷ 1 5/7 = 7/12
Hence,
Marna's rate = 7/12 - 1/4
Marna's Rate = (7 - 3) / 12 = 4/12 = 1/3
Marna's rate = 1/3
Hence, time it takes Marna = reciprocal of rate = 1÷ 1/3 = 1 * 3/1 = 3 hours
For a linear function: The graph is a straight line
For a non-linear function: The graph is not a straight line
The given graph is not a straight line and is rather a curve with several turning points i.e several ups and downs. Hence the graph belongs to a Non-Linear Function.
A relation is non-function when it passes through same x value more than once. Since this cannot be observed in the given graph, the graph belongs to a function.
Therefore, the correct answer to this question is "Non-Linear Function"
