Are the following lines parallel, perpendicular, or neither: x=6 and x=12 Please show work or explain
Answer:
x=6 and x=12 are parallel.
Step-by-step explanation:
If you graph x=6 it will be a straight verticle line on the x-axis where 6 is, same with x=12 (put a vertical line on 12 for the x-axis). When you put these both on the same graph you see they are directly across from each other but will never touch. Therefore, they are parallel. If you are writing this on paper, simply draw a graph to show this.
During the early part of the 1994 baseball season, many sports fans and baseball players noticed that the number of home runs being hit seemed to be unusually large. Below are separate stemplots for the number of home runs by American League and National League teams based on the team-by-team statistics on home runs hit through Friday, June 3, 1994 (from the Columbus Dispatch, Sunday, June 5, 1994). Legend: 2|9 represents 29. What is the mean for the number of home runs for the National League teams
Complete Question
The picture of the stem plot National and American League is shown on the first uploaded image
Answer:
The value is [tex]\= x = 50.14[/tex]
Step-by-step explanation:
From the question we are told that
The stem plot for National League is
[tex]2\ \ \ \ \ 9\\3\ \ \ \ \ 1 \\4\ \ \ \ \ 2\ 6\ 7\ 8\ 8\\5 \ \ \ \ \ 3\ 5\ 5\ 5\\6 \ \ \ \ \ 3\ 3\ 7\\7[/tex]
The sample size is n = 14
Generally the stem plot is interpreted in this manner
The numbers on the first column represents the tens of a two digit number while the second column holds the possible unit number the tens in the first column can be combined with
for example 4th row
5 3 5 5 5
is equivalent to
53 55 55 55
Generally the mean for the national league is mathematically represented as
[tex]\= x = \frac{29 + 31 + \cdots + 67}{14}[/tex]
=> [tex]\= x = \frac{702}{14}[/tex]
=> [tex]\= x = 50.14[/tex]

The graph would have a 2 with an open circle above it. The line would cover all numbers greater than 2.
Step-by-step explanation:
6x-5(2x-1)<4-2x
6x-10x+5<4-2x
-4x+5<4-2x
-4x+2x<4-5
-2x<-1
x>-1÷(-2) (You flip the sign when you multiply or divide both sides by a negative number)
x>2
Four times the sum of some number plus 2 is equal to 8 times the number minus 16.
Answer:
x=9/2
Step-by-step explanation:
4x+2=8x-16
-4x=-18
4x=18
x=18/4
x=9/2
The number is 6.
Let the unknown number be represented with y
This formula can be derived from the question: 4 (y + 2) = 8y - 16
In order to determine the value of y, take the following steps:
Combine similar terms
8 + 16 = 8y - 4y
Add similar terms
24 = 4y
Divide both sides by 4
y = 6

The approximate heights of two of the world's tallest mountains are given. Determine which is the taller mountain and by how many meters. Round to the nearest meter. Dhaulagiri l: 8167 meters and Manaslu: 26,781 feet Click the icon to view a table of English and Metric Equivalents. The taller mountain, Dhaulagiri 1 , is taller by approximately (Round to the nearest meter as needed.) meters.
Answer:
The taller mountain is Dhaulagiri, by approximately 4 meters.8163
Step-by-step explanation:
You first need to convert the height of Manaslu to cm using the table, so you multiple 26,781 feet by 30.48 cm to get 816284.88. Then you need to convert that to meters, so you divide by 100 to get 8162.8488. Lastly you round that and subtract it from 8167 to see how much taller it is.

4. A bakery can make 58 packages of cookies
in one hour. There are 24 cookies in each
package. Which is the best estimate of the
number of cookies the bakery makes in one
hour.
a. 12,000
b. 120
c. 1,200
Show work to support your answer.
Answer:
C
Step-by-step explanation:
58*24=1392, which is closest to 1200.
Or, you could round the numbers to the nearest tens place, which would give you 60*20, giving you the exact answer of 1200. I think this was the preferred way of solving it.

A certain number of sixes and nines is added to give a sum of 126; if the number of sixes and nines is interchanged, the new sum is 114. How many of each were there originally?
Answer:
Original number of sixes = 6
Original number of nines = 10
Step-by-step explanation:
We are told in the question that:
A certain number of sixes and nines is added to give a sum of 126
Let us represent originally
the number of sixes = a
the number of nines = b
Hence:
6 × a + 9 × b = 126
6a + 9b = 126.....Equation 1
If the number of sixes and nines is interchanged, the new sum is 114.
For this second part, because it is interchanged,
Let us represent
the number of sixes = b
the number of nines = a
6 × b + 9 × a = 114
6b + 9a = 114.......Equation 2
9a + 6b = 114 .......Equation 2
6a + 9b = 126.....Equation 1
9a + 6b = 114 .......Equation 2
We solve using Elimination method
Multiply Equation 1 by the coefficient of a in Equation 2
Multiply Equation 2 by the coefficient of a in Equation 1
6a + 9b = 126.....Equation 1 × 9
9a + 6b = 114 .......Equation 2 × 6
54a + 81b = 1134 ........ Equation 3
54a + 36b = 684.........Equation 4
Subtract Equation 4 from Equation 3
= 45b = 450
divide both sides by b
45b/45 = 450/45
b = 10
Therefore, since the original the number of nines = b,
Original number of nines = 10
Also, to find the original number of sixes = a
We substitute 10 for b in Equation 1
6a + 9b = 126.....Equation 1
6a + 9 × 10 = 126
6a + 90 = 126
6a = 126 - 90
6a = 36
a = 36/6
a = 6
Therefore, the original number of sixes is 6
Classify the equilibrium solutions as asymptotically stable or unstable. Entry field with incorrect answer is unstable, is unstable, is unstable. is unstable, is asymptotically stable, is unstable. is asymptotically stable, is unstable, is asymptotically stable. is asymptotically stable, is asymptotically stable, is unstable. is unstable, is asymptotically stable, is asymptotically stable.
Answer:
asymptotically stable.
Step-by-step explanation:
Equilibrium solutions in which solutions that starts near and then moves away from equilibrium solutions are asymptotically unstable. Equilibrium solutions which solutions starts nears and then move towards the equilibrium are asymptotically stable.
Use linear approximation to approximate √25.3 as follows.
Let f(x)=√x. The equation of the tangent line to f(x) at x=25 can be written in the form y=mx+b. Compute m,b.
Using this, find the approximation for √25.3.
The idea is to use the tangent line to [tex]f(x)=\sqrt x[/tex] at [tex]x=25[/tex] in order to approximate [tex]f(25.3)=\sqrt{25.3}[/tex].
We have
[tex]f(x)=\sqrt x\implies f(25)=\sqrt{25}=5[/tex]
[tex]f'(x)=\dfrac1{2\sqrt x}\implies f'(25)=\dfrac1{10}[/tex]
so the linear approximation to [tex]f(x)[/tex] is
[tex]L(x)=f(5)+f'(5)(x-5)=5+\dfrac{x-5}{10}=\dfrac x{10}+\dfrac92[/tex]
Hence [tex]m=\frac1{10}[/tex] and [tex]b=\frac92[/tex].
Then
[tex]f(25.3)\approx L(25.3)=\dfrac{25.3}{10}+\dfrac92=\boxed{7.03}[/tex]

The function h (x) = StartFraction 2 (x + 3) Over x EndFraction is a result of the composition (g compose f) (x). If g (x) = StartFraction 2 over x EndFraction, what is f(x)?
Answer:
[tex]f(x) = \frac{2x}{2x + 3}[/tex]
Step-by-step explanation:
Given
[tex]h(x) = \frac{2x + 3}{x}[/tex]
[tex]g(x) = \frac{2}{x}[/tex]
[tex]g(f(x)) = h(x)[/tex]
Required
Find f(x)
[tex]g(x) = \frac{2}{x}[/tex]
Substitute x for f(x)
[tex]g(f(x)) = \frac{2}{f(x)}[/tex]
Recall that
[tex]g(f(x)) = h(x)[/tex]
This gives
[tex]\frac{2}{f(x)} = \frac{2x + 3}{x}[/tex]
Cross Multiply
[tex]f(x) * (2x + 3) = 2 * x[/tex]
[tex]f(x) * (2x + 3) = 2 x[/tex]
Make f(x) the subject of formula
[tex]f(x) = \frac{2x}{2x + 3}[/tex]
Answer:
x/x+3
Step-by-step explanation:
Given the function h (x) = 2x + 4, for which value of x does h (x) = 18?
The required value for which h(x) = 18 is given as x = 7.
What are functions?Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Here,
The function h(x) = 2x + 4 - - - - (1)
Since h(x) =18
Substitute h(x) = 18 in equation 1,
18 = 2x + 4
Simplify
18 - 4 = 2x
x = 14 / 2
x = 7
Thus, the required value for which h(x) = 18 is given as x = 7.
