Answer:
shoulda woulda coulda been B
Step-by-step explanation:
The total number of gifts = x+y.
The inequality is:
Key chains cost $1, Magnets $0.50
Total Cost = x + 0.5y
Inequality is:
Without graphing you can solve system by using substitution:
This is one solution where the maximum x value is given.
So the most keychains that can be purchased is 16. However, because magnets are cheaper, more can be purchased as long as cost remains under 20.
If you solve both inequalities for "y", you get the upper and lower bounds for how many magnets can be purchased given a quantity of keychains.
This is complete solution which gives all possible combinations.

Answer:
6
Step-by-step explanation:
you have 24 ballons, so you divide them by how many groups you can make, 4, then you have the equation 24/4, which equal 6
if you have any questions, leave them in the comments and i will try to answer them, if this helped, pls give brainliest
Part A:
Let the length of one of the sides of the rectangle be L, then the length of the other side is obtained as follow.
Let the length of the other side be x, then
Thus, if the length of one of the side is x, the length of the other side is 8 - L.
Hence, the area of the rectangle in terms of L is given by
Part B:
To find the domain of A
Recall that the domain of a function is the set of values which can be assumed by the independent variable. In this case, the domain is the set of values that L can take.
Notice that the length of a side of a rectangle cannot be negative or 0, thus L cannot be 8 as 8 - 8 = 0 or any number greater than 8.
Hence the domain of the area are the set of values between 0 and 8 not inclusive.
Therefore,
