The true option about the solution to the system of inequalities shown is B. The second line has a positive slope and goes through (0, negative 3) and (1, 0).
<h3>How to explain the inequality?</h3>Plot these ordered pairs on a coordinate plane and connect them by straight lines.
The sign of both inequalities is "<"which means both lines are dotted and everything below the lines is shaded.
From the below graph it is clear that all values are satisfied.

Answer:
3.728 cm²
90
Step-by-step explanation:
To built the envelope I am using a rectangular piece of material 28 m long and 12 m wide.
Out of this material, I have to cut patches that are 1/12 the length and 2/15 the width of the whole material.
So, the length of the patches is m and the width of the patches is
m.
Therefore, the area of the patches is (1.6 × 2.33) = 3.728 m² each. (Answer)
Now, the area of the rectangular piece of material is (28 × 12) = 336 m²
Hence, ≈ 90 such patches can be made out of the whole material. (Answer)
