Would lines Y=-1/10x+6 and 10y+x=-100be perpendicular parallel or neither? I just need a brief explanation with the answer
Answers
Given:
The given equations are,
\(\begin{gathered} y=-\frac{1}{10}x+6\text{ . .. . . . . (1)} \\ 10y+x=100\text{ . . . . . .(2)} \end{gathered}\)The objective is to find whether these two lines are parallel, perpendicular or neither.
Explanation:
The general eqauation of straight line is,
\(y=mx+b_{}\)Here, m represents the slope of the straight line, b represents the y intercept.
For parallel lines, the slope value of both the lines will be equal.
\(m_1=m_2\)For perpendicular lines, the slope value both the lines will be opposite and inverse.
\(m_1=-\frac{1}{m_2}\)To find slope of line 1 and line 2:
By comparing the general equation with the equation (1), the slope value of equation (1) will be,
\(m_1=-\frac{1}{10}\)The equation (2) can be solved as,
\(\begin{gathered} 10y+x=100 \\ 10y=-x+100 \\ y=-\frac{1}{10}x+\frac{100}{10} \\ y=-\frac{1}{10}x+10 \end{gathered}\)Now, by comparing the above equation with the general equation, the slope value of line 2 will be,
\(m_2=-\frac{1}{10}\)Thus, the slope value of line 1 and line 2 are equal which is -(1/10).
Hence, these two lines are parallel lines.

two equal, opposite sides,two intersecting and non-equal diagonals, andopposite angles that are equalThe area of a parallelogram can be calculated by multiplying its base with the altitude. The base and altitude of a parallelogram are perpendicular to each other. The formula to calculate the area of a parallelogram can thus be given as,
Area of parallelogram = b × h square units

As part of their employee benefits , all workers at Middletown Electronics receive a pension that is calculated by multiplying the number of years worked times 1.56% of the average of their three highest years’ salary. Maureen has worked for Middletown for 30 years and is retiring. Her highest salaries are $107,000, $107,800, and $108,198. Calculate Maureen’s pension.
Answers
Maureen's pension would be $50,035.20.
What is Percentage?
To compute a percentage, divide the value by the entire amount and multiply the result by 100. A percentage is a quantity or ratio that is stated as a fraction of one hundred. The percent sign, "%," is frequently used to represent it.
First, we need to calculate the average of Maureen's three highest salaries:
Average = (107,000 + 107,800 + 108,198) / 3
Average = 322,998 / 3
Average = 107,666
Next, we need to calculate 1.56% of this average:
Percentage = 1.56% * 107,666
Percentage = 1,667.84
Finally, we multiply this percentage by the number of years worked to find the pension:
Pension = 30 * 1,667.84
Pension = 50,035.20
So, Maureen's pension would be $50,035.20.

Suppose y varies directly with x. When x is 5, y is 15. What is y when x is 12?
Answers
Answer:
y = 36
Step-by-step explanation:
given y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
to find k use the condition when x = 5 , y = 15
15 = 5k ( divide both sides by 5 )
3 = k
y = 3x ← equation of variation
when x = 12 , then
y = 3 × 12 = 36

What is ethnic separatism?Ethnic Separatism is the process by which a nation or ethnic group makes efforts to become more autonomous from the central government of a state, or even secedes, when it is unhappy with any combination of social, economic, and political conditions in the nation in which it is located.
When an ethnic group actively works to assert its rights and importance, ethnic nationalism is the result. When it serves the interests of the state, governments may support ethnic nationalism as a project; however, for a variety of reasons, ethnic nationalism may also pose a threat to the state. Separatism based on ethnicity is one of these causes. Find out what ethnic separatism is, some examples of it, and more by continuing to read.

Step-by-step explanation:
in 10 hrs distance covered=speed×time=15×10=150 nautical miles.
x²=600²+150²-2×600×150×cos 20°
x²=360,000+22,500-180,000×cos 20°
x=√(382,500+180,000×cos 20°)
x\approx 742.73 nautical miles
time taken=742.73/15 \approx ~49.52 hours
total time taken=10+49.52=59.52 hours
applying sine formula
\(\frac{sin ~B}{150} =\frac{sin~20}{742.73} \\\sin~B=\frac{150}{742.73} \times~sin~20\\B=\sin^{-1} [\frac{150}{742.73} \times \sin~20]\\B\approx~3.96 ^\circ\\B\approx 4^\circ\)

The equation which would produce a parabola from the provided options are equation first and forth,

How to identify the type of conic section from an equation?To of identify the type of conic section from an equation whether it is parabola, or not, let suppose the equation as,
\(Ax^2+By^2+Cx+Dy+E=0\)
If In this equation,
Either \(A=0\) or \(B=0\), but not both. Then it is the equation of parabola.
The first equation is,
\(-5x^2 + 4x - 7y + 14 = 0\)
There is no square term of y. Thus, this is the equation of parabola.
The second equation is,
\(-x^2 + 6x + y^2 - 8 = 0\)
This is not the equation of parabola, as there is two square terms of variable x and y.
The third equation is,
\(9x^2 - 12xy + 4y^2 + 4x - y + 5 = 0\)
Similar to the second equation, here is also two square terms of different variable. Thus, it is not a equation of parabola.
The fourth equation is,
\(12x + 6y -5y^2 + 14 = 0\)
This equation is the equation of parabola, as there is only a single square term.
The fifth equation is,
\(20x^2 + 10xy - y^2 + 3x - 6y + 5 = 0\)
This is now the equation of parabola because of two square terms.
Hence, the equation which would produce a parabola from the provided options are equation first and forth,
\(-5x^2 + 4x - 7y + 14 = 0\)
\(12x + 6y -5y^2 + 14 = 0\)

Alexa opens a retirement account and is starting with $100. He plan to add $25 each month to the account ? What’s is the equation and how much money will Alexa have after 6 months and after 12 months ?
Answers
Answer:
The equation to calculate the balance in the account after "x" months would be: y = 100 + 25x
And after 6 months, Alexa would have $250 in his retirement account, and after 12 months, he would have $400 in his account.
Step-by-step explanation:
Let's call the balance in Alexa's retirement account after "x" months "y".
The equation to calculate the balance in the account after "x" months would be:
y = 100 + 25x
After 6 months, Alexa would have added 6 * $25 = $150 to the original balance of $100, so the balance would be:
y = 100 + 25 * 6 = 100 + 150 = $250
After 12 months, Alexa would have added 12 * $25 = $300 to the original balance of $100, so the balance would be:
y = 100 + 25 * 12 = 100 + 300 = $400
So, after 6 months, Alexa would have $250 in his retirement account, and after 12 months, he would have $400 in his account.
