The following gives the variations:
m= -4p -----------> direct variation
r=9/t----------->indirect variation
n=(1/2)f----------->direct variation
u=2/z----------->indirect variation
The value of y when x=2 is -14
<u>What are direct and indirect variations ?</u>
One quantity directly changes in response to a change in another quantity, which is referred to as direct variation. This suggests that if one quantity increases, the other will follow suit and rise in proportion. In a similar manner, if one quantity declines, the other amount also declines.
When one parameter declines while the other rises or vice versa, this is known as inverse variation. This means that the magnitude or absolute value of one item decreases as the other quantity rises, resulting in a constant value for their product. This item is also referred to as the proportionality constant.
m= -4p -----------> direct variation
r=9/t----------->indirect variation
n=(1/2)f----------->direct variation
u=2/z----------->indirect variation
General equation for an indirect variation:
y = k/x
substitute y=7 and x= -4
7=k/-4
k=7*-4 = -28
To find y when x=2:
Substitute x=2 and k=-28 into the equation
y=-28/2 = -14
