8. A man has a collection coins made up of nickels and quarters with a total value of $6.65. If he has 5 more quarters than nickels, how many of each coin does ne
have?

9. The length of a rectangle 4 more than twice its width. If the perimeter of the
rectangle is 98 cm, find its area.

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
