Answer:
x = 2/3
Step-by-step explanation:
The approach usually recommended for almost any problem involving fractions is to "clear fractions" first. Here, that means multiplying both sides of the equation by 2x (the least common denominator). After that, divide both sides by the coefficient of x.
[tex]\dfrac{2}{x}=\dfrac{6}{2}\qquad\text{given}\\\\\dfrac{(2x)(2)}{x}=\dfrac{(2x)(6)}{2}\qquad\text{multiply by $2x$}\\\\4=6x\qquad\text{simplify}\\\\\dfrac{4}{6}=x\qquad\text{divide by 6}\\\\\boxed{x=\dfrac{2}{3}}\qquad\text{reduce the fraction}[/tex]
__
After you have done this a few times, you recognize that the process involves multiplying the original equation by 2x/6 = x/3. This is x times the reciprocal of the constant term on the right. You can "cut to the chase" and do multiplication of both sides by x/3 as your first step:
[tex]\dfrac{2}{x}\cdot\dfrac{x}{3}=\dfrac{6}{2}\cdot\dfrac{x}{3}\qquad\text{multiply the given equation by $\dfrac{x}{3}$}\\\\\dfrac{2}{3}=x\qquad\text{simplify}[/tex]

An airplane descends 1.6 miles to an elevation of 6.95 miles. Find the elevation of the plane before its

The initial elevation of the plane was
Smiles.
Answers
Answer:
Step-by-step explanation: First, let's call the starting elevation of the plane: e
We can then write an equation representing this problem as:
e−1.5mi=5.25mi
Now, add 1.5mi to each side of the equation to solve for e
while keeping the equation balanced:
e−1.5mi + 1.5mi=5.25mi + 1.5mi
e−0=6.75mi
e=6.75mi
The plane's starting elevation was 6.75 miles

Often sales of a new product grow rapidly at first and then level off with time. This is the case with the sales represented by the function S(t)=500−400t−1, where t represents time in years. Find the rate of change of sales for the following number of years.
a.1
b.10
Answers
Answer:
Here we have the function:
S(t) = 500 - 400*t^(-1)
Then the rate of change at the value t, will be:
S'(t) = dS(t)/dt
This differentiation will be:
S'(t) = -400/t^2
Then:
a) the rate of change at t = 1 is:
S'(1) = -400/1^2 = -400
The rate of change after one year is -400
b) t = 10
S'(10) = -400/10^2 = -400/100 = -4
The rate of change after 10 years is -4, it reduced as the years passed, as expected.

Write an equation of the form y = mx for the line shown below.
Answers
Answer:
y = -3x
Step-by-step explanation:
To get slope intercept, you divide both y values by both x values like this
[tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]
In this case this will be [tex]\frac{(-3 - 6)}{(1 - (-2))}[/tex]
This will become [tex]\frac{-9}{3}[/tex]
Divide those two to get -3, and now you get your slope intercept.

What is piecewise function?Piecewise function is a function built from pieces of different functions over different intervals.
The given function is: f(x)= [tex]\left \{ {{2x, \;\; x < 1} \atop {-4, \;\; x=1} \right \atop {x+8, \;\; x > 1}[/tex]
As, piecewise function is a function built from pieces of different functions over different intervals.
As per the above discussion we can say that,
Take function for limit 1 minus, as f(x) = 2x
put x=1,
f(x)=2, exits.
Take function for limit 1 plus, as f(x) = x+8
put x=1,
f(x)=9, exits.
As both satisfies the definition and part (A)
As well as both limit exist and are not equal.
So, Limit of f (x) = 2 as x approaches 1 minus. Limit of f (x) = 9 as x approaches 1 plus for the given f(x).

Step-by-step explanation:

What is the interquartile range?An interquartile range is a measure of the difference between the upper and lower quartiles of a dataset.
W can find the values of the upper and lower quartile and median from a box plot.
The middle line is the median and the first line is the lower quartile and the last line is the upper quartile.
The formula used is Upper quartile - Lower quartile.
We have,
The range of a dataset is calculated as the difference between the maximum and minimum values in the dataset.
In this case, the range is:
Range = highest value - lowest value = 34 - 16 = 18
The interquartile range (IQR) is the difference between the third quartile (Q3) and the first quartile (Q1). In this case, the IQR is:
IQR = Q3 - Q1 = 29 - 21 = 8
So the difference between the range and the IQR is:
Range - IQR = 18 - 8 = 10
Therefore,
The difference between the range and the IQR of the data set represented by the box plot is 10.

Answer: System 1 has an infinite number of solutions and System II has no solutions.
Step-by-step explanation:
If we look at system 1, we see that if we multiply the first equation by 2 and subtract the y value so that its on the same side as x, the equations are the same. That means that no matter the x or y value, it will be a solution.
If we look at system 2, however, we see that if we multiply the top equation by 3, the equations are the exact same except for the fact that the top equation has a -21. This means that no matter the x or y, there will never be a solution.

f(4) = -18
g(-3) = -76
Step-by-step explanation:
f(x) = -5x + 2
f(4) = -5(4) + 2
= -20 + 2
= -18
g(x) = 3x^3 + 5
g(-3) = 3(-3)^3 + 5
= 3(-27) + 5
= -81 + 5
= -76
Answer:
F(4)= -18
G(-3)=-76
f(x)= -5x+2
g(x)=3x^3+5
To find f(4), wherever you see x in f(x) put in 4
-5(4)+2= -18
To find g(-3), wherever you see x in g(x) put -3
3(-3)^3 +5= -76
