(1) y = 7x , (2) y = 11x , (3) y = 9x , (4) y = 28x
given y varies directly as x then y = kx ( k is the constant of variation )
(1) find k using the given conditions k = 
= 
= 7
equation is y = 7x
(2) k = 
= 11
equation is y = 11x
(3) k = 
= 9
equation is y = 9x
(4) k = 
= 28
equation is y = 28x
Answer:
base of the triangle = 12 m
Explanation:
Area of the triangle = 1/2 * base * height
We are given that:
area = 54 m^2
height = 9 m
Substitute in the equation to get the base as follows:
Area of the triangle = 1/2 * base * height
54 = 1/2 * base * 9
108 = 9*base
base = 12 m
Hope this helps :)
