Answer:
The system of inequalities is equal to
The graph in the attached figure
Step-by-step explanation:
Let
x------> the number of gallons of iced tea
y-----> the number of gallons of lemonade
we know that
-----> inequality A
-----> inequality B
using a graphing tool
the solution is the shaded area
see the graph in the attached figure
Remark
You need a split statement like C or D. A and B would have to be considered if the ages were between 12 and 60. However the discounts apply the other way. Up to 12 and over 60. You need two inequalities to describe this.
<em><u>Under 12</u></em>
x ≤ 12
The pointy end of the arrow points toward the x. x must be less than or at most equal to 12. The pointy end of the inequality must be directed towards the smaller number.
<em><u>Over 60</u></em>
x ≥ 60
This time the pointy end is directed towards the 60. x must be at least 60 and then upwards.
So C is the correct answer.
13/8 or in a mixed number is 1 and 5/8
2 onea and 8 tens is a way to express it
Answer:
