Answer:
Part 1) The graph in the attached figure N 1
Part 2) The graph in the attached figure N 2
Part 3) The graph in the attached figure N 3
Part 4) The graph in the attached figure N 4
Step-by-step explanation:
Part 1) we have
Find the inverse
Let
y=f(x)
Exchange the variables x for y and y for x
isolate the variable y
------> inverse function
see the attached figure N 1
Part 2) we have
Find the inverse
Let
y=f(x)
Exchange the variables x for y and y for x
isolate the variable y
------> inverse function
see the attached figure N 2
Part 3) we have
Find the inverse
Let
y=f(x)
Exchange the variables x for y and y for x
isolate the variable y
------> inverse function
see the attached figure N 3
Part 4) we have
Find the inverse
Let
y=f(x)
Exchange the variables x for y and y for x
isolate the variable y
------> inverse function
see the attached figure N 4
The total cost if the cafeteria makes the pizza is:
cost = 44.20 + 6.25 p
where p is the number of pizza
while the cost if it is ready made is:
cost (ready made) = 14.50 p
Equating the two to find for x:
44.20 + 6.25 p <
14.50 p
p > 5.35
So it is cheaper when 6 pizzas or more is made
100 ounces, 200 ounces, 200 pounds, 1000 pounds, 25,000 ounces, 7 tons, then 16,500 pounds.
Answer:
7
Step-by-step explanation;
Rewriting our equation with parts separated:
4+1/7+2+6/7
Solving the whole number parts:
4+2=6
Solving the fraction parts:
1/7+6/7=7/7 <em>(7/7 is a whole number) </em>But first before simplifing, reduce the fraction, 7/7=1/1. Then 1/1=1.
Combining the whole and fraction parts:
(Solving the whole number parts - 6)
(Solving fraction parts - 1)
<h2>6+1 = 7</h2>
