Q1. System of inequalities.
There is a club that is baking strawberry and apple pies for a bake sale, the problem is to write and graph a system of inequalities, so let be:
x: The number of strawberry pies
y: The number of apple pies
Then we can write these system of inequalities as follows:
First statement. They need at most 18 pies:
(1) [tex]x+y \leq 18[/tex]
Second statement. They cannot have more than 12 apple pies:
(2) [tex] y \leq 12[/tex]
So the system of inequalities is given by:
[tex]\left \{ {{x+y \leq 18} \atop {y \leq 12}} \right.[/tex]
Q2. Graph.
The graph of these inequalities is shown in the figure below. As you can see the solution is the shape in gray.

Q2. Graph.
The graph of these inequalities is shown in the figure below. As you can see the solution is the shape in gray.
Let
x--------> the number of strawberry pies
y--------> the number of apple pies
we know that
[tex] x+y \leq 18 [/tex]
equation [tex] 1 [/tex]
[tex] y \leq 12 [/tex]
equation [tex] 2 [/tex]
Part a) Write a system of inequalities to model this system
the answer part a) is
[tex] x+y \leq 18 [/tex]
[tex] y \leq 12 [/tex]
Part b) Graph a system of inequalities to model this system
Using a graph tool
