Answer:
Yes
Step-by-step explanation:
We have two properties for our question :
(4, 27)
y = 3x + 15
We are being asked whether the point (4, 27) is a solution of y = 3x + 15
So how do we figure this out? Well, what we have to know first that (4, 27) represents a variable, 4 which is the run on the graph, represents x in a solution. And 27 which is the rise on the graph, represents y in the solution. So when asking for a solution with two points, all we must do is substitute x and y for the two coordinates.
y = 3x + 15
y = 27 and x = 4
27 = 3(4) + 15
27 = 12 + 15
27 = 27
Since this equation is true with the respected variables, therefore signifies that (4,27) is a solution of y = 3x + 15

Step-by-step explanation:
7. Solve for x:

Separate variable and numbers into different sides of inequality:

Divide the inequality by 3:

8. Solve for x:

Eliminate the brackets:

Separate variable and numbers into different sides of inequality:

Divide the inequality by 10:

9. Solve for x:

Solve two inequalities
and
separately:

and

So,

10. Solve for x:

Add 1:

Divide by 3:

Assume the price of the CD is x.
x+0.05x=15
x=14.29
