Sagot :
The equation of direct variation given that y varies directly with x.
y is 15 when x is 11 will be [tex]y = \dfrac{15}{11} x[/tex].
What is proportionality?
The proportional relationship between x and y can be written symbolically as
[tex]x \propto y[/tex]
That middle sign is called the sign of proportionality.
Variation: Direct from y to x:
[tex]x \propto y[/tex]
y = 15, x= 11
Write the equation
[tex]x \propto y[/tex]
Express as an equation
[tex]y = kx[/tex]
Where k is the constant of variation
Substitute
y = kx
15 = 11k
Solve for k
k = 15/11
Substitute in [tex]y = kx[/tex]
[tex]y = \dfrac{15}{11} x[/tex]
Thus, the equation of direct variation given that y varies directly with x.
y is 15 when x is 11 will be [tex]y = \dfrac{15}{11} x[/tex].
