Answer:
a) 
b) 
If we want to minimize the cost then we should rent the Acme Truck company.
Step-by-step explanation:
Assuming the following questions.
(a) Find the daily cost of leasing from each company as a function of the number of miles driven and sketch the graph of these functions.
For the Ace truck we know that leases its 10-ft box truck at $20/day and $0.50/mi. So then f(x) representing the daily cost is given by:
Where x represent the number of miles driven
For the Acme Truck we know that leases a similar truck at $15/day and $0.55/mi, so then the g*x( representing daily cost would be given by:
Where x represent the miles driven.
We can see the plot on the figure attached.
(b) Which company should you rent a truck from for 1 day if you plan to drive 70 miles and wish to minimize cost?
If we replace the value x=70 for both functions we got:
If we want to minimize the cost then we should rent the Acme Truck company.
Answer:
Step-by-step explanation:
Given, value of y = 4
To find : Value of x
plug the value of y
Multiply the numbers : 4 and 4
Move 16 to right hand side and change it's sign
Add the numbers : 65 and 16
Divide both sides by 3
Calculate
Hope I helped!

Answer:
The new class average for number of siblings is 3 5/26 or 3.1923
Step-by-step explanation:
if the average is 3 siblings per student and there are 25 students, it means that we can calculate the number of siblings
25 * 3 = 75
we add the 8 new siblings and we also add the student
75 + 8 = 83
25 + 1 = 26
To find the new average of siblings per student, we divide the number of siblings by the number of students.
83 / 26 = 3 5/26
the new class average for number of siblings is 3 5/26 or 3.1923
Answer:
a
Step-by-step explanation:
Step-by-step explanation:
To figure out your x-intercepts and y-intercepts you have to redo the equation and make it equal to zero.
Step 1: 8x + 9y - 72 = 0
Step 2: 8x + 9y = 72
Now you can figure out your intercepts! As long as you use the STANDARD FORM EQUATION which is Ax + By = C
Y-INTERCEPT (vertical line): ( 
, 0 )
X-INTERCEPT (horizontal line): ( 0 , 
)
Insert your numbers how it shows in the standard form equation and you should get something like this:
Y-INTERCEPT: ( 
, 0 )
<em>Simplified Y-INTERCEPT: </em>( 8 , 0 )
X-INTERCEPT: ( 0 , 
)
<em>Simplified X-INTERCEPT: </em><em> ( 0 , 9 )</em>
<em />
Insert that into your graph and you should be able to get your answer.
