Heya!!!!
Answer to your question:
B)-3 <-1
As we all know, negative three is less than negative one.
We can also do it this way,
We know
3>1
multiplying by negative sign to both sides, therefore sign of inequality changes
we get
-3 <-1
Hope it helps *_*
- I tried solving this but I don't think there's a perimeter for that.
Answer:
a) ![f(x) = 0.5 \frac{dollars}{day} x + 20](https://tex.z-dn.net/?f=%20f%28x%29%20%3D%200.5%20%5Cfrac%7Bdollars%7D%7Bday%7D%20x%20%2B%2020)
![g(x) = 0.55 \frac{dollars}{mi} x + 15](https://tex.z-dn.net/?f=g%28x%29%20%3D%200.55%20%5Cfrac%7Bdollars%7D%7Bmi%7D%20x%20%2B%2015)
b) ![f(70)=0.5*70 +20 =55](https://tex.z-dn.net/?f=%20f%2870%29%3D0.5%2A70%20%2B20%20%3D55)
![g(70)= 0.55*70 + 15 =53.5](https://tex.z-dn.net/?f=%20g%2870%29%3D%200.55%2A70%20%2B%2015%20%3D53.5)
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:
![f(x) = 0.5 \frac{dollars}{day} x + 20](https://tex.z-dn.net/?f=%20f%28x%29%20%3D%200.5%20%5Cfrac%7Bdollars%7D%7Bday%7D%20x%20%2B%2020)
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:
![g(x) = 0.55 \frac{dollars}{mi} x + 15](https://tex.z-dn.net/?f=g%28x%29%20%3D%200.55%20%5Cfrac%7Bdollars%7D%7Bmi%7D%20x%20%2B%2015)
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:
![f(70)=0.5*70 +20 =55](https://tex.z-dn.net/?f=%20f%2870%29%3D0.5%2A70%20%2B20%20%3D55)
![g(70)= 0.55*70 + 15 =53.5](https://tex.z-dn.net/?f=%20g%2870%29%3D%200.55%2A70%20%2B%2015%20%3D53.5)
If we want to minimize the cost then we should rent the Acme Truck company.
Ur x axis will be the number of cans and ur y axis will be the weight in oz
u will label ur x axis( the number of cans) in intervals of 1......from 0 to 4
u will label ur y axis (the weight) in intervals of 10....from 0 to 40
ur equation would be : y = 10x
points on this line are : (0,0), (1,10), (2,20), (3,30), (4,40)

Step-by-step explanation:
![x - 12 = - 4](https://tex.z-dn.net/?f=x%20-%2012%20%3D%20%20-%204)
![put \: like \: terms \: together\\ x = - 4 + 12 \\ solve\\ x = 8](https://tex.z-dn.net/?f=%20put%20%5C%3A%20like%20%5C%3A%20terms%20%5C%3A%20together%5C%5C%20x%20%3D%20%20-%204%20%20%2B%2012%20%5C%5C%20%20solve%5C%5C%20x%20%3D%208)
