6x−6=6x+15 Please solve this equation, i'll put the brainliest if its the right answer
Answers
Answer:
Step-by-step explanation:
6x-6=6x+15
or, -6+6x=15+6x
adding -6x in both sides
or, -6 + 6x + -6x = 15 + 6x + -6x
Combine like terms: 6x + -6x = 0
or, -6 + 0 = 15 + 6x + -6x
or, -6 = 15 + 6x + -6x
Combine like terms: 6x + -6x = 0
or, -6 = 15 + 0
or, -6 = 15
Solving
-6 = 15
Couldn't find a variable to solve for.
This equation is invalid, the left and right sides are not equal, therefore there is no solution.

The displacement vector r=2i-j+3k is aligned to the same direction as the force (F) whose magnitude is F =20N Determine the comple description of the force F
Answers
Answer:
Step-by-step explanation:
Displacement vector R = 2i + j + 3k
Unit vector along displacement vector
= R / I R I
= ( 2i + j + 3k ) / √ ( 2² + 1² + 3² )
= ( 2i + j + 3k ) / √ 14
Now force F acts in the direction of this unit vector . It is magnitude of 20 N
So this vector can be represented by the following expression
F = 20 [ ( 2i + j + 3k ) / √ 14 ]

Five test scores have a mean (average score) of 90, a median (middle score) of 91 and a mode (most frequent score) of 94. Find the sum of the two lowest test scores.
Answers
Answer:
171 points.
Step-by-step explanation:
If five test scores have a mean of 90, all the scores added together will be 5 * 90 = 450.
The middle score is 91, so the other four scores added together will be 450 - 91 = 359.
The mode is higher than the median, so we can assume that the highest two numbers are the same: 94. 94 * 2 = 188. 359 - 188 = 171.
That means that the sum of the two lowest test scores is 171 points.
Hope this helps!
Answer:
The sum of the two lowest test scores is 171.
Step-by-step explanation:
We see that there are 5 test scores, so the median ( middle score ) was not taken to be the average of the two middle scores. It is an element present in the set of five test scores. The mode of course has to be present in the set, but multiple times. If we can figure out how many times this mode is present in the set, it would help us.
As 91 is the middle value, there has to be two above 91. Therefore, as 94 appears the most frequent, is must appear twice.
Now another key thing we need here is the sum of all 5 numbers. Given a mean of 90, 90 [tex]*[/tex] 5 = the sum of all 5 numbers = 450. Therefore, the sum of the two lowest test scores should be = 450 - 94 - 94 - 91 = 171 - which is our solution.

Which point on the graph of g(x)=(1/5)^x? HELPP
Answers
Answer:
(-1,5) and [tex](3, \frac{1}{125})[/tex] are points on the graph
Step-by-step explanation:
Given
[tex]g(x) = \frac{1}{5}^x[/tex]
Required
Determine which point in on the graph
To get which of point A to D is on the graph, we have to plug in their values in the given expression using the format; (x,g(x))
A. (-1,5)
x = -1
Substitute -1 for x in [tex]g(x) = \frac{1}{5}^x[/tex]
[tex]g(x) = \frac{1}{5}^{-1}[/tex]
Convert to index form
[tex]g(x) = 1/(\frac{1}{5})[/tex]
Change / to *
[tex]g(x) = 1*(\frac{5}{1})[/tex]
[tex]g(x) = 5[/tex]
This satisfies (-1,5)
Hence, (-1,5) is on the graph
B. (1,0)
x = 1
Substitute 1 for x
[tex]g(x) = \frac{1}{5}^x[/tex]
[tex]g(x) = \frac{1}{5}^1[/tex]
[tex]g(x) = \frac{1}{5}[/tex]
(1,0) is not on the graph because g(x) is not equal to 0
C. [tex](3, \frac{1}{125})[/tex]
x = 3
Substitute 3 for x
[tex]g(x) = \frac{1}{5}^x[/tex]
[tex]g(x) = \frac{1}{5}^3[/tex]
Apply law of indices
[tex]g(x) = \frac{1}{5} * \frac{1}{5} * \frac{1}{5}[/tex]
[tex]g(x) = \frac{1}{125}[/tex]
This satisfies [tex](3, \frac{1}{125})[/tex]
Hence, [tex](3, \frac{1}{125})[/tex] is on the graph
D. [tex](-2, \frac{1}{25})[/tex]
x = -2
Substitute -2 for x
[tex]g(x) = \frac{1}{5}^x[/tex]
[tex]g(x) = \frac{1}{5}^{-2}[/tex]
Convert to index form
[tex]g(x) = 1/(\frac{1}{5}^2)[/tex]
[tex]g(x) = 1/(\frac{1}{5}*\frac{1}{5})[/tex]
[tex]g(x) = 1/(\frac{1}{25})[/tex]
Change / to *
[tex]g(x) = 1*(\frac{25}{1})[/tex]
[tex]g(x) = 25[/tex]
This does not satisfy [tex](-2, \frac{1}{25})[/tex]
Hence, [tex](-2, \frac{1}{25})[/tex] is not on the graph

You are going to make “words” using the letters in the word WHISKAS. a) How many seven-letter words can you make? b) How many seven-letter words can you make if the two S’s must be together? c) How many seven-letter words can you make if the words must begin with A and end with H?
Answers
Hey there! I'm happy to help!
PART A
When we say words, we don't really mean words. We just mean how many different ways we can arrange the letters. We could make a word like Hiskasw and that would work.
We have six different letters: w, h, i, s, k, and a. We have two s's and this will be very important when finding these permutations.
The first thing we do is take the number of letters and find its factorial. In this case, it is seven, so we have 7×6×5×4×3×2×1=5040.
But, this is not how many combinations there are, because we have two s's, and since they are the same many of our combinations are actually identical, but the s's are just switched. So, we take the number of s's (2) and we factorial it, which just still equals two, and then we divide our first factorial by that.
5040/2=2520
There are 2520 ways you can arrange the word WHISKAS.
PART B
Let's think of the seven letter slots in the word. It doesn't matter where you place one of the S's, but a slot next to the first S you place only has one choice of letter, which is another S to make it adjacent. This means that one specific slot is required to have an S. If we start off filling in our required one with an S, we have six letters left to fill in our other slots, which will give us a result of 6!, which is 720 seven-letter words.
PART C
Now, we have to have A be the first term and H be the last. If we think of the seven letter slots, we have only one choice on the first one, which is A, and only one choice on the last one, which is H. This leaves us with 5! or 120 possibilities, but we also have to divide by two because we have two S's, so there are 60 seven-letter words you can make if the words must begin with A and end with H.

Which equation represents the vertical asymptote of the graph? a curve asymptotic to y equals 0 from negative x to negative y near x equals 12. A curve asymptotic to y equals 0 from positive x to positive y near x equals 12. x = 0 y = 0 x = 12 y = 12
Answers
Answer:
The correct option is x = 12
Step-by-step explanation:
An asymptote of a function is a line to to which the function converges to as it tends to infinity such that the function gets infinitesimally close to its asymptote but the function will not reach or cross its asymptote. That is the separating distance between the function and the asymptote tends to zero as either the x or y coordinates, or both the x and y coordinates tend to infinity.
A vertical aymptote, is one parallel to the y-axis and it is given by the value of the x-coordinate where it occurs
In the graph of the question, the vertical asymptote occurs at x = 12 and it is the line x = 12.
From the given graph, it can be said that the vertical asymptote will be formed at x=12. Option C is correct.
The given curve represents a function which is defined for all value fo x except 12.
The following information can be extracted from the graph of the function;
The function is defined for all values of x except 12.The function has a horizontal asymptote at y=0.The function forms a vertical asymptote at x=12. The curve approaches negative infinity from the left of 12 and approaches positive infinity from right of 12.Based on the above conclusions, it can be said that the vertical asymptote will be formed at x=12. Option C is correct.

Answer:
A.) P^2 - 10p + 24 = 0
B.) 6 or 4 dollars
Step-by-step explanation:
Given that a company’s weekly revenue, in thousands, is modeled by the equation
R = -p2 + 14p,
where p is the price of the product it makes. The company is considering hiring an outside source to distribute its products, which will cost the company 4p + 24 thousand dollars per week.
If the company want to break even, the cost of hiring distributors will be equal to the revenue per week.
Therefore,
-P^2 + 14p = 4p + 24
Collect the like terms
-P^2 + 14p - 4p - 24 = 0
-P^2 + 10p - 24 = 0
Multiply all by minus sign
P^2 - 10p + 24 = 0
B.) To find P, factorize the equation above.
P^2 - 10p + 24 = 0
- 6 x - 4 = 24 and - 6 - 4 = 10
P^2 - 4p - 6p + 24 = 0
P( p - 4 ) - 6( p - 4 )
P - 6 = 0 or p - 4 = 0
P = 6 or 4
Substitute both back into the equation to test their authenticates
When p = 6
6^2 - 10(6) + 24 = 0
When p = 4
4^2 - 10(4) + 24 = 0

Answers
Answer:
The distance Ted will run in 285 minutes is 60 km
Step-by-step explanation:
The information in the question states as follows;
The distance Ted can run in 95 minutes = 20 km
Therefore, from the equation of speed, we have;
Speed = Distance covered ÷ Time taken
Ted speed, s = 20 km/(95 minutes) = 4/19 = 0.21 km/minute
Therefore, the distance, d Ted will cover in 285 minutes is given as follows;
d = Speed × Time = 0.21 km/minute × 285 minutes = 60 kilometres
The distance Ted will run in 285 minutes = 60 kilometres.

May be it's help you;)
Answer:
The length of each of the two equally long sides is 26 cm
The length of the longer side is 36 cm
Step-by-step explanation:
Let the length of each of the two equal sides be represented by x
The other side = 10 + x
Perimeter of triangle (P) = sum of all sides of the triangle
88 = x + x + 10 + x
88 = 3x + 10
3x = 88 - 10
3x = 78
x = 78/3 = 26
Length of each of the two equally long sides (x) = 26 cm
Length of the longer side = 10 + x = 10 + 26 = 36 cm

Step-by-step explanation:
A) ∠QRS = 90 degrees (The angle of the triangle opposite to the diameter is always 90)
Given that QR = 68 degrees
So,
∠RSQ = [tex]\frac{1}{2} (QR)[/tex]
∠RSQ = 68/2
∠RSQ = 34 degrees
Now, Finding ∠RQS
∠RQS = 180-90-34
∠RQS = 56 degrees
B) ∠SRT = ∠QRS - ∠QRT
=> ∠QRS = 90 (Mentioned above) , ∠QRT = 56 (Given)
So,
∠SRT = 90-56
∠SRT = 34 degrees

is the square root of 29 rational or irrational?
Answers
Answer:
irrational
Step-by-step explanation:
rational - a number that can turn into a fraction (you could do this with a perfect square)
Irrational - a number that cannot be expressed as a fraction
The square root of 29 is an irrational number because it can not be expressed as a fraction.
To determine whether the square root of 29 is rational or irrational, we need to check if it can be expressed as a fraction (ratio) of two integers.
Assuming that the square root of 29 is rational, we can represent it as √29 = a/b, where a and b are integers with no common factors other than 1, and b is not equal to 0.
Squaring both sides of the equation (√29)² = (a/b², we get 29 = (a²)/(b²).
This implies that 29 is equal to the ratio of two integers (a²)/(b²), which means that 29 can be expressed as a fraction. However, this is not true because 29 is a prime number and cannot be written as a fraction of two integers.
Therefore, the square root of 29 cannot be expressed as a fraction and is therefore irrational.
Hence, the square root of 29 is an irrational number.
