Answer:
y =7x , follows the direct variation.
Step-by-step explanation:
Direct variation states that a relationship between two variables in which one is a constant multiple of the other. In other words, when one variable changes the other changes in proportion to the first.
If y is directly proportional to x i.e, or
y = kx .....[1] where k is the constant variation
Given : y = 7x
On comparing this with equation [1] we get;
k(constant of variation) = 7
therefore,
it follows the direct variation as or
y = 7x where k =7 is the constant of variation.
Therefore, y =7x follows the direct variation.

Answer:
6 and 7
Step-by-step explanation:
To do this, we need to look at the two closest numbers that are divisible by 6. These are 36 and 42.
As 37 is between 36 and 42, the quotient must be between 6 and 7
Answer:
Here the answer, dearie.
Step-by-step explanation:
So, 136 people can sit in cafeteria and the patio.
So we are given a system:
Substitute x = 2 we get the system:
Multiply the first equation by -5 and the second by 2 we get the system:
Adding the two equations we get :
We find the value of y by using any of the other equations like this:
Final solution:
