Lydia writes the equation below with a missing value.

y=5x-[]

She puts a value in the box and says that the equation represent a direct variation. Which explains whether the equation could represent a direct variation?

A. The equation has a minus sign, so it cannot represent a direct variation.
B. If she puts 5 in the box, she would have a direct variation.
C. If she puts 0 in the box, she would have a direct variation.
D. The equation is not of the form y = kx, so it cannot represent a direct variation.

If she puts 0 in the box she would have a direct variation.

Step-by-step explanation:

 Given : Lydia writes the equation y = 5x - __ with a missing value.

She puts a value in the box and says that the equation represents a direct variation.We have to choose the correct option from the given options that explain that  the equation could represent a direct variation.When two variables are such that one is a constant multiple of other, we said they are in Direct variation.

That is in form of y = ax , here y and x are in direct variation.Consider the given equation y = 5x  - __

For the equation to be in direct variation the value of missing term has to be 0.

then equation becomes,y = 5x

Thus, If she puts 0 in the box she would have a direct variation.

Option (a) is correct.

unpaid balance is : $149.99-$50 = $99.99 new balance = 149.99+2.62-50 = $102.61 finance charge = 99.99- 0.21/12= $1.75 new balance = 99.99+1.75 = $101.74 average daily balance method average daily balance= 3399.70/30 = $113.32 finance charge = $ 0.21/12ă—113.32 = $1.98 new balance = $149.99-50+1.98 = $101.97
