Answer:
z=4
Step-by-step explanation:
1/4z-2/7=5/7
1/4z= 5/7+2/7
1/4z=1
z=4

Answer:
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation ( or direct variation) if it can be expressed in the form
or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
we have the point (6,-2)
so
Find the constant of proportionality k
Simplify
therefore
The equation of the direct variation is
