To determine and graph the system of inequality.
Explanation of Solution
Given:
Student artwork is 20 feet long
Some pieces are 8.5 inch wide
Other pieces are 11 inch wide
Leave 3 inch of space to the left of each art piece
Post at least 16 pieces of art
Calculation:
Let
Now,
Need to leave 3 inch of space to the left of each art piece.
So, adding 3 to the width of the painting
Inequality I:
Here, the slope is
Inequality II:
Here, the slope is
Graph:
Here
Interpretation:
Therefore, the dark green shaded region is the solution of the system of inequation.
