The first thing we must do for this case is to define variables.
We have then:
x: number of slices
y: total cost
We write the linear function that relates the variables.
We have then:
Then, we evaluate the number of slices to find the total cost.
-two slices cost:
We substitute x = 2 in the given equation:
Answer:
two slices = 2.2 $
-ten slices cost:
We substitute x = 10 in the given equation:
Answer:
ten slices = 11 $
-half a slice cost:
We substitute x = 1/2 in the given equation:
Answer:
half a slice = 0.55 $
The answer is d because x is horizontal
Answer:
Step-by-step explanation:
Divide 42 by 12 so the unit rate is $3 per headband
Answer:
Analyzed and Sketched.
Step-by-step explanation:
We are given 
.
We need to find the following to sketch the graph.
1) First derivative of y with respect to x to determine the interval where function increases and decreases.
2) Second derivative of y with respect to x to determine the interval where function is concave up and concave down.
The roots are x = -1/2 and x = 1/2 but negative one cannot be possible due to logarithmic function.
x = 1/2 is absolute maximum.
So, concavity is always down.
Here, x = 0 is vertical asymptote.
I attached the picture of sketched graph.
