She is incorrect because 27 is not a prime number but yet it has 7 at the end
Using the graph that is included, look at the points given. For example (30, 3). There would be 30 vegetarian dishes and 3 steak dinners for a total of 33 meals. If that is plugged into the cost equation 20(30)+3(30) it would equal $690. The next point (33, 1) would cost 20(33) + 30(1) = $690 and but gives 34 meals. However, 34 vegetarian meals would only cost 20(34)=$680 and have 34 meals.
If both types of meals need to be purchased, 33 vegetarians and 1 steak. If only vegetarians are purchased, the cost is cheaper by $10.
Answer:
False
Step-by-step explanation:
To find the area of the square, you multiply length by length, adding the length of all 4 sides would be the perimeter
Answer:
Step-by-step explanation:
I graphed this on my calculator to get the region of feasibility. You should learn how to use your calculator to help you do things like this. You should know by now how to graph by hand, which is tedious, so now it's time to use your calculator to sweat the small stuff and learn to do some useful things.
When you graph this inequality on your calculator, you can see the points of intersection which in turn translate to the vertices of the feasible region. They are located at:
(-14, -6), (-9, -11), (6, 4)
You could then use those vertices to maximize the profit equation or production equation or whatever it is this system pertains to.
