Answer:
Solution :
{x,y} = {3,7}
Step-by-step explanation:
Answer:
Option A.
Step-by-step explanation:
The general form of a quadratic function is
It means, power of y should be 1 and highest power of x should be 2.
In option A,
It is a quadratic function.
In option B,
Here, power of y is 2. So, it is not be a quadratic function.
In option C,
Here, highest power of x is 3. So, it is not be a quadratic function.
In option D,
Here, highest power of x is 1. So, it is not be a quadratic function.
Therefore, the correct option is A.
The inequality becomes :
350B+525F≤4500
Explanation:
Let the number of basil plants be represented by = B
Let the number of fennel plants be represented by = F
As each basil plant needs 350 ml of water, so B basil plants will need 350*B = 350B ml of water
Similarly, each fennel plant needs 525 ml of water so F fennel plants will need 525*F = 525F ml of water.
And both the plants need to be watered with a maximum of 4500 ml of water.
So inequality becomes: 350B+525F≤4500
I think that the answer is B. I tried to read more about the question to understand it more but got nothing out of it.
Answer:

Step-by-step explanation:
The exponential function that decrease by 15% every time x increases by 1 is given by:

We simplify the parenthesis to get:

Therefore the decrease by 15% every time x increases by 1 is

The second choice is correct.
