Answer:</h2>
Shown below
<h2>
Step-by-step explanation:</h2>
The first system of inequality is the following:
To find the solution here, let's take one point, say, and let's taste this point into both inequalities, so:
<h3>FIRST CASE:</h3>
First inequality:
The region is not the one where the point lies
Second inequality:
The region is the one where the point lies
So the solution in this first case has been plotted in the first figure. As you can see, there is no any solution there
<h3>SECOND CASE:</h3>
First inequality:
The region is the one where the point lies
Second inequality:
The region is not the one where the point lies
So the solution in this first case has been plotted in the second figure. As you can see, there is a solution there.
CONCLUSION: Notice that when reversing the signs on both inequalities the solution in the second case is the part of the plane where the first case didn't find shaded region.
Answer:
So, its better to buy larger bag
Step By Step Explanation:
Let
Smaller bag hold = x ounces
Price of x ounce in smaller bag = $ y
Price of 1 ounce in smaller bag = ....(1
Larger bag will hold = x + 10 ounces
Price of x+10 ounces in larger bag = y + 1.5
Price of 1 ounce in larger bag = ...(2
Now equation 1 tells that 1 ounce in smaller costs , and equation 2 tells in ounce in larger bag costs .
Now as we can see, we can get equation 2 from equation 1 by increasing numerator by 1.5 and denominator by 10. In this case denominator has increased more than numerator so the value of overall fraction would be less than . It means our larger bag has less price per ounce.
So, its better to buy larger bag
