D) 1•x=5, 1•5=5 8•5=40, the answer is 40/5 CDs
E) 3/3=1, 26.25/3= 8.75. The answer is 1/8.75
F) 10/10=1, 120/10= 12. The answer is 1/12
G) 2•x=12, 2•6=12, 120•6= 720. The answer is 12/720

Step-by-step explanation:
Answer:
y=2x+3
Step-by-step explanation:
Answer:
D. Infinitely many solutions
Step-by-step explanation:
1.Since neither equation contains an isolated. However, we can isolate -y in the first equation by adding 
to both sides.
Like this: 
ending up with 
2.Now, we can change y to a positive y. By doing so, we divide -y by the entire equation.
Like this 
Ending with 
3.Now, we can plug the expression 
into the second equation as a substitute for y, and solve for x. Then, we can use x to calculate y.
Like this 
4. Since -2x+2x would cancel out and leave -30=-30. This is true because we know -30 equals -30 with no variable in sight.
By evaluating the <em>linear</em> function f(x) = x - 3 at x = 5 and discarding the another function in the table given, we conclude that f(5) = 2 belongs to that <em>linear</em> equation.
<h3>What function contains a given relationship?</h3>
In this problem we must check if the given relationship between the <em>independent</em> variable (x) and the <em>dependent</em> variable (y) exists in any of the two functions: (i) a table, (ii) an expression.
After a quick analysis, we conclude that f(5) = 2 is a point of the linear function f(x) = x - 3. Here is the proof:
f(5) = 5 - 3
f(5) = 2
