Determine whether the equation represents a direct variation. if it does, find the constant of variation. 2y=5x+1

we know that

A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form or

In a direct variation the equation of the line passes through the origin

In this problem we have

----> this line not passes through the origin

therefore

The answer is

the equation does not represent a direct variation

step-by-step explanation:

what does 'mandy have ben 780 bottle caps. ' mean?

answer would be 8.64 or s = 11π/4 inches

step-by-step explanation:

s = r θ  

where s = arc length  

r = radius = 3 inches  

θ = central angle in radians = ( π /180)*165  

s = 3(π/180)*165  

= 8.64 inches
