Answer:
A. None
General Formulas and Concepts:
<u>Algebra I</u>
- Perpendicular Lines/Intersecting Lines have 1 solution.
- 2 identical Lines have infinitely many solutions.
- Parallel Lines have no solution.
Step-by-step explanation:
According to the graph, we see that we have 2 parallel lines. Therefore, there will be no solution.
Answer:
Tema = 26 years
Juma = 13 years
Abdul = 26 years
Step-by-step explanation:
Let their ages be represented as:
Tema = x
Juma = y
Abdul = z
From the question, we are told that:
Juma is twice as old as Abdul
y = 2z
z = y/2
= 0.5y
And Juma is a half times as old as Tema.
y = 1/2x
y = 0.5x
x = y/0.5
x = 2y
Hence,
x + y + z = 65
2y + y + 2y = 65
= 5y = 65
y = 65/5
y = 13 years
Since y = Zuma's age, Zuma is 13 years old
From the above question
Since 2y = z
y = 13
2 × 13 = z
z = 26
Since z = Abdul's age, Abdul is 26 years old
From the above question
x = 2y
y = 13 years
x = 2 × 13 years
x = 26 years.
Since x = Tema's age
Tema is 26 years.
Therefore, their present ages are:
Tema = 26 years
Juma = 13 years
Abdul = 26 years
cot x = cos x / sin x
cot x = .85 / .52 = 1.6346
