Introduction
In this assignment, we will examine a series of mathematical problems reliant on algebraic methods. The problems range in complexity and involve solving systems of equations, analyzing ordered pairs, and applying algebra to real-world scenarios. Each problem requires the implementation of distinct algebraic techniques such as substitution, elimination, and graphical representation. We will evaluate whether specific ordered pairs satisfy these systems of equations while deriving points of intersection and solutions that exemplify practical applications in areas such as finance and scientific calculations.
Problem 1: Determining Solutions of an Ordered Pair
We need to evaluate whether the ordered pair (1, 8) satisfies the system of equations. Suppose our equations are:
1. \( y = 2x + 6 \)
2. \( y = -x + 9 \)
Solution:
Substituting x = 1 into the first equation:
\[
y = 2(1) + 6 = 8
\]
Retaining the same y-value in the second equation,
\[
8 = -1 + 9 = 8
\]
Since both equations satisfy \( y \), the ordered pair (1, 8) is indeed a solution to the given system of equations.
Problem 2: Solving Systems by Substitution
Consider the following system:
1. \( y = 3x + 2 \)
2. \( 2x + y = 12 \)
Solution:
Step 1: Substitute \( y \) from the first equation into the second equation.
\[
2x + (3x + 2) = 12
\]
Step 2: Combine like terms:
\[
5x + 2 = 12
\]
Step 3: Isolate \( x \):
\[
5x = 10 \implies x = 2
\]
Step 4: Substitute \( x \) back to find \( y \):
\[
y = 3(2) + 2 = 8
\]
Thus, the solution to the system is \( (2, 8) \).
Problem 3: Solving the System by Addition
Given the equations:
1. \( 3x + 2y = 16 \)
2. \( x - 2y = -2 \)
Solution:
Step 1: Multiply the second equation by 2 to prepare for addition.
\[
2(x - 2y) = 2(-2) \implies 2x - 4y = -4
\]
Step 2: Rewrite the equations:
1. \( 3x + 2y = 16 \)
2. \( 2x - 4y = -4 \)
Now we have:
\[
(3x + 2y) + (2x - 4y) = 16 - 4 \implies 5x - 2y = 12
\]
Step 3: Solve for one variable. Let's isolate \( y \):
\[
2y = 5x - 12 \implies y = \frac{5x - 12}{2}
\]
Using the second equation we previously adjusted can lead to finding \( x \), thus calculating both variables more thoroughly.
Problem 4: Graphing the System of Equations
Let’s analyze the following linear equations:
1. \( y = x + 3 \)
2. \( y = -2x + 1 \)
Graphical Solution:
- To determine the intersection points graphically, create a sketch based on the equations provided.
- The solution set lies where these lines intersect.
Conclusion on Consistency:
The lines intersect at a single point, indicating a consistent system with a unique solution.
Real-World Application Example
Breaking Even for a Venue:
The venue charges per ticket and the total number of attendees (x) will dictate costs.
Equation Formation:
Let \( c(x) = 70x \)
The fixed cost of the concert can vary based on the number of attendees. The break-even point occurs when revenue equals cost.
Thus, we solve:
\[
70x = fixed costs
\]
For instance, if fixed costs are 00:
\[
70x = 1400 \implies x = 20
\]
This means the venue breaks even with 20 ticket sales.
Sales Modeling for a Boutique:
If the startup cost for a boutique is ,000 and each floral arrangement costs to create, while selling for :
1. \( 25n - 17n = 15000 \)
Thus, solving for \( n \):
\[
8n = 15000 \implies n \approx 1875
\]
This indicates the boutique needs to sell approximately 1875 arrangements to reach break-even.
Animal Shelter Problem:
Let \( c \) represent cats, \( d \) denote dogs, and \( g \) denote guinea pigs.
1. \( g = \frac{1}{3}d \)
2. \( d = c + 40 \)
3. \( c + d + g = 254 \)
Substituting and solving these equations aids in determining how many of each animal is in the shelter.
