Answer:
D. (1, -2)
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
<u>Algebra I</u>
- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define systems</u>
5x - 2y = 9
3x + 4y = -5
<u>Step 2: Rewrite systems</u>
10x - 4y = 18
3x + 4y = -5
<u>Step 3: Solve for </u><em><u>x</u></em>
- Add to equations together: 13x = 13
- Divide 13 on both sides: x = 1
<u>Step 4: Solve for </u><em><u>y</u></em>
- Define: 3x + 4y = -5
- Substitute in <em>x</em>: 3(1) + 4y = -5
- Multiply: 3 + 4y = -5
- Isolate <em>y </em>term: 4y = -8
- Isolate <em>y</em>: y = -2
And we have our final answer!
The best design for Camille is the one in which the area matches the total of material she wants to use for each pillow.
<h3>What should Camille consider for her design?</h3>
Camille's main restriction is the material per pillow since she needs every pillow to use only 36 inches of material. Due to this, she needs to make sure the design meets this requirement.
<h3>How to determine how much material each design requires?</h3>
The best method for this is to calculate the area of the design by using the sides. Here are the most common formulas:
- Triangular design: Base x height/ 2
- Squared or rectangular design: side x side
- Circular design: A = π r²
Based on this, the best design is the one that adjusts to the material available.
Note: This question is incomplete because there is no information about the designs; due to this, I answered it based on general knowledge.
