Answer:
The graph of the function 
is attached as image below.
Analysis:
We have two intersection points in the graph
The function intersects the y-axis at points (0,4)
The function intersects the x-axis at points (-16,0)
f(x) is positive for x>-`16
f(x) is negative for x<-`16
A) Because the 80 is by itself that would be the start up fee.
B) We are told x is the number of months. Since the X is being multiplied by 30, we know that would be the total monthly cost. This is being added to the 80, which does not have an exponent, so we know this is a single cost, which would be the start up fee.
C) Copying the same format as the given equation above, change the numbers:
f(x) = 20 + 35x
D) I used the same format as the first equation, which meant replacing the start up cost from the original one ( 80) with the start up of the new one (20). Then I changed the monthly cost from the original one (30) with the monthly cost of the new one (35).
E) Replace x in each equation with 8 and calculate the cost of each:
80 + 30(8) = 80 + 240 = $320
20 + 35(8) = 20 + 280 = $300
The second club (club B) is the cheaper option for her.
Answer:
below
Step-by-step explanation:
improper fraction: 14/5
as a decimal: 2.8
proper fraction: 2 4/5
To simplify, you must distribute the 2 into the 5x and -4 by multiplying 2 with 5x and 2 with -4.
<span>2(5x – 4) + 3x
2 x 5x = 10x
2 x -4 = -8
You will get 10x - 8 + 3x
Now you must combine like terms or add like terms. In this case we must add 10x and 3x
10x + 3x = 13x
Finally the answer would be 13x - 8</span>
