We have been given an equation . We are asked to find constant of proportionality from our given equation.
We know that two directly proportional equations are in form ,where y is directly proportional to x and k is constant of proportionality.
Let us rewrite our given equation by cross multiplying as:
Now we will divide both sides of equation by 2.
We can see that our equation is in form and constant of proportionality is .
Answer:
A) 14x + 2
Step-by-step explanation:
(2x + 2x) + (5x + 5x) + (1 + 1)
= 4x + 10x + 2
= 14x + 2
You can only add 4x and 10x since they both have a variable (x). You cannot add 2 since 2 doesn't have a variable, so the answer in simplest form is 14x + 2
