14.99n+4.99 represents the cost of n cds
(14.99x3) + 4.99 =
34. 97 + 4.99= $39.97- 0.1= $39.96
3 CD s cost $39.96
I think the answer is d. -11
Explanation:
Replace the variable x with 3 in the expression.
f(3)=-2•3-5
Multiply -2 by 3
f(3)=-6 -5
Subtract 5 from -6
f(3)= -11
Then the answer should be -11.
Answer:
See explanation
Step-by-step explanation:
You are given the equation
1. When x = 0, then
When y = 0, then
When x = 3, then
Complete the table:
2. Use the table of values to graph the line. Plot two points (0,8) and (6,0) and connect them with a straight line. See attached diagram for details.
The domain is the input of the function or n in this case. So, in the boxes, you would put [1, 2, 3, 4, 5, 6, ...]
The range is the output of the function or f(n) in this case. So, in the boxes, you would put [4, 6, 8, 10, 12, 14, ...]
