A horizontal asymptote is a straight line that a function approaches as x approaches infinity or negative infinity.
For the function f(x) = (x-2)/(x^2 + 1):
Horizontal asymptotes:
As x approaches infinity or negative infinity, the highest degree term in the numerator and denominator are the same, which is x^2. Therefore, we can use the ratio of the coefficients of the highest degree terms to determine the horizontal asymptote. In this case, the coefficient of x^2 in both the numerator and denominator is 1. So the horizontal asymptote is y = 0.
Vertical asymptotes:
Vertical asymptotes occur when the denominator of a rational function equals zero and the numerator does not. So, to find the vertical asymptotes of f(x), we need to solve the equation x^2 + 1 = 0. However, this equation has no real solutions, which means that there are no vertical asymptotes for f(x).
For the function f(x) = (x-2)/(x^2 - 11):
Vertical asymptotes:
To find the vertical asymptotes, we need to solve the equation x^2 - 11 = 0. This equation has two real solutions, which are x = sqrt(11) and x = -sqrt(11). These are the vertical asymptotes of f(x).
Horizontal asymptotes:
As x approaches infinity or negative infinity, the highest degree term in the numerator and denominator are x and x^2 respectively. Therefore, the horizontal asymptote is y = 0. However, we also need to check if there are any oblique asymptotes. To do this, we can use long division or synthetic division to divide the numerator by the denominator. After doing this, we get:
x - 2
--------------
x^2 - 11 | x - 2
x - sqrt(11)
------------
sqrt(11) + 11
sqrt(11) + 2
--------------
-9
Since the remainder is a non-zero constant (-9), there are no oblique asymptotes. So the only asymptotes for f(x) are the vertical asymptotes x = sqrt(11) and x = -sqrt(11).

Quick algebra 1 question for 50 points!
Only answer if you know the answer, quick shout-out to Yeony2022, tysm for the help!
Answer:
b
Step-by-step explanation:
b shows direct variation because we can clearly tell that the slope of the graph is 1/2. The graph is also linear, and it crosses the origin (0,0).
a: This graph can be represented as y=2, and that is not a direct variation.
b: Above explanation. This graph is a direct variation.
c: This graph can be represented as x=-8, and that is not a direct variation.
d: This graph has the slope, but it does not cross the origin, so it is not a direct variation.
Answer:
Graph b
Step-by-step explanation:
Direct variation means "y varies directly as x”:
Direct variation equation:
[tex]y=kx[/tex]
where k is the (non-zero) constant of variation.
Note, therefore, that a direct variation equation passes through the origin, as when x = 0:
[tex]\implies y=k(0) \implies y=0[/tex]
Graph a
y does not change as x varies.
Therefore this graph does not model a direct variation.
Graph b
As x gets bigger, so does y. As x gets smaller, so does y.
The line passes through the origin (0, 0).
Therefore this graph models a direct variation.
Graph c
x does not change as y varies.
Therefore this graph does not model a direct variation.
Graph d
As x gets bigger, so does y. As x gets smaller, so does y.
However, the line does not pass through the origin (0, 0).
Therefore this graph does not model a direct variation.
Describe the steps you would take to solve the given literal equation for m as shown.
For finding the given literal equation is necessary to apply the power 2 on both sides of the given equation and after that you should rewrite the equation as a function of the variable m .
Power RulesThere are different power rules, see some them:
1. Multiplication with the same base: you should repeat the base and add the exponents.
2. Division with the same base: you should repeat the base and subctract the exponents.
3.Power. For this rule, you should repeat the base and multiply the exponents.
4. Zero Exponent. When you have an exponent equals to zero, the result must be 1.
The question gives: [tex]t=2\pi *\sqrt{\frac{m}{k}}[/tex] and from the previous equation, you should find [tex]m=\frac{kt^2}{4\pi ^2}[/tex].
STEP 1 - Applying the power 2 on both sides of the equation [tex]t=2\pi *\sqrt{\frac{m}{k}}[/tex].
[tex]t=2\pi *\sqrt{\frac{m}{k}}\\ \\ t^2=(2\pi *\sqrt{\frac{m}{k}})^2\\ \\ t^2=4\pi ^2*\frac{m}{k}[/tex]
STEP 2 - Rewriting the equation [tex]t^2=4\pi ^2*\frac{m}{k}[/tex] as a function of the variable m .

(-4, 8) and (6, 2). Slope
Answer:
In order to go from the first point to the second, we need to rise from 4 to 7, i.e. by 3. We also need to run from -4 to -2, i.e. by 2. Therefore the slope is 32 .
Step-by-step explanation:
On a number line, point D is at -6, and point E is at 8. Point F lies between points D and E. If DF: FEis 3: 1, where does point F lie on the
number line?
F is located on the number 4.5 on the number line.
Where does point F lie on the number line?We know that point D is at -6
Point E is at 8.
Point F is between D and E, such that the ratio:
DF:FE is 3:1
So if we divide the distance between D and E in 4 parts, 3 of these parts are DF, and one of these parts is FE.
First, the distance between E and D is:
distance = 8 - (-6) = 14 units.
Now, if we divide that by 4, we get:
14/4 = 3.5
Then we have:
DF = 3*(3.5) = 10.5
This means that F is at 10.5 units to the right of D, then:
F = D + 10.5 = -6 + 10.5 = 4.5
F is located on the number 4.5 on the number line.

Step-by-step explanation:
Think about it this way
a point with an x value of 4,
this x value is put into the function,
then the function outputted a y value (or value) of 5.
So, we can name this function f(x)
Then, we let x = 4,
then the output for f(4) = 5
Answer: f(4) = 5

Which equation can be used to find y, the year in which both bodies of water have the same amount of mercury? 0.05 – 0.1y = 0.12 – 0.06y 0.05y 0.1 = 0.12y 0.06 0.05 0.1y = 0.12 0.06y 0.05y – 0.1 = 0.12y – 0.06
The equation that can be used to find y, the year in which both bodies of water have the same amount of mercury is 0.05 + 0.1y = 0.12 + 0.06y. Hence, the 3rd option is the right choice.
In the question, we have been asked for the equation that can be used to find y, the year in which both bodies of water have the same amount of mercury.
First, we will find the equations showing the level of mercury in each body of water.
For the first water body:
Initial measure of mercury = 0.05 ppb.
Rate of rising = 0.1 ppb each year.
Number of years = y.
Thus, the equation showing level of mercury = 0.05 + 0.1y.
For the second water body:
Initial measure of mercury = 0.12 ppb.
Rate of rising = 0.06 ppb each year.
Number of years = y.
Thus, the equation showing level of mercury = 0.12 + 0.06y.
We are looking for the equation, to find y, the year in which both bodies of water have the same amount of mercury.
As they will have the same amount of mercury, their respective equations showing the level of mercury should be equal, that is:
0.05 + 0.1y = 0.12 + 0.06y, which is the required equation.
Thus, the equation that can be used to find y, the year in which both bodies of water have the same amount of mercury is 0.05 + 0.1y = 0.12 + 0.06y. Hence, the 3rd option is the right choice.
