Is x-y=3 a direct variation

No, it is not a direct variation

Explanation:

The given equation solves to y = x-3, which is not in the form y = kx. So the original equation is not a direct variation.

An example of a direct variation would be y = 5x, where in this case, k = 5.

Visually, all direct variation equation graphs go through the origin.

step-by-step explanation:

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
