Hannah has a jar filled with 150 coins made up of quarters and nickels. the total value of the coins is $28.30

if x represents the number of quarters in the jar, what is an equation that can be used to find the number of quarters? & how many quarters and how many nickels are there?

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
