9. Darcy is buying apples and oranges for a large fruit basket to give away as a door prize at a charity event. Apples cost $0.2

4 each and oranges cost $0.80 each. She has $12 to spend and would like to purchase at least 20 pieces of fruit total.
a) Write a system of linear inequalities to represent
this situation, then graph.
b) Using your graph, give two possible combinations
of apples and oranges Darcy can buy.

Assume that the number of apples is x and the number of oranges is y.

For the first given, we know that each apple costs $0.24 and each orange costs $0.8, therefore:
amount paid for apples = 0.24x and amount paid for oranges = 0.8y
we also know that the total amount spent is $12, therefore the first equation is as follows:
0.24x + 0.8y = 12

For the second given, we know that the total number of fruit bought is 20, therefore, the second equation is:
x + y = 20

You can easily graph these two functions and find a possible combination from the graph (the correct combination would be the intersection between the two lines).

You graph the function f(x)=-|×|-12
Firlakuza [10]

Answer:

See attachment

Step-by-step explanation:

We want to graph f(x)=|x|-12 on the interval -10 to 10.

Let g(x)=|x| be the parent absolute value function.

We can easily graph f(x)=|x|-12, if we use translation.

When the parent function is shifted downwards by 12 units, we obtain the graph of f(x)=|x|-12.

The parent function is a v-shaped graph with vertex at the origin.

We shift the parent function down so that its vertex is now at (0,-12) to get the graph of f(x)=|x|-12 .

See attachment for the graph of f(x)=|x|-12  on the specified interval.

Is -5/12 and irrational or rational
oksian1 [2.3K]

Answer:

Rational.

Step-by-step explanation:

Since it can be put into a fraction, negative or positive it is clearly rational. Irrational numbers are numbers we can never know the true value because they repeat forever (pi for example)
