Answer:
negative 5. or -5
Step-by-step explanation:
f(-1)= (-1)2-3
2 times -1= -2
-2-3= -5
f= -5
Answer:
hope it helps...
Step-by-step explanation:
The value of the constant of proportionality is k=5k=5
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y/x=ky/x=k or y=kxy=kx
The value of the constant k is equal to the value of the slope
In this problem we have
y=5xy=5x ------> is a linear direct variation
The slope is m=5m=5
therefore
The value of the constant of proportionality is k=5k=5
Answer:
![x=-2 \ \ \ and \ \ \ y=1](https://tex.z-dn.net/?f=x%3D-2%20%20%5C%20%5C%20%5C%20and%20%5C%20%5C%20%5C%20%20y%3D1)
Step-by-step explanation:
Suppose numbers are <em>x</em> and <em>y</em>
<u>Product of </u><em><u>x</u></em><u> and </u><em><u>y</u></em><u> is </u><em><u>-2</u></em>
<u />![xy=-2](https://tex.z-dn.net/?f=xy%3D-2)
And sum of <em>x</em> and <em>y</em> is <em>-1</em>
![x=-2 \ \ \ and \ \ \ y=1](https://tex.z-dn.net/?f=x%3D-2%20%20%5C%20%5C%20%5C%20and%20%5C%20%5C%20%5C%20%20y%3D1)
3/2 = 9/x,
so 9 times 2 divided by 3 = 6
A: 6
