which formula defines the sequence f(1)=2, f(2)=6, f(3)= 10, f(4)= 14,f(5)=18
The formula that defines the sequence is Tn = 4n - 2
Given the following sequence 2, 6, 10, 14, 18
From the sequence:
First-term a = 2
Common difference d = 6 - 2 = 10 - 6 = 4
Since there is a common difference, the sequence is an arithmetic sequence.
The nth term of the arithmetic sequence is expressed as:
[tex]T_n=a+(n-1)d[/tex]
Substitute the given data into the formula:
[tex]T_n=a+(n-1)d\\T_n=2+(n-1)(4)\\T_n=2+(4n-4)\\T_n=2+4n-4\\T_n=4n-2\\[/tex]

What is the solution to the system of linear equations?
-8x-7y=96
-3x+5y=-25
Enter your answer in the boxes
Answer:
[tex]x = -5[/tex]
[tex]y = -8[/tex]
Step-by-step explanation:
Given
[tex]-8x - 7y = 96[/tex]
[tex]-3x + 5y = -25[/tex]
Required
Determine x and y
Make y the subject of formula in the second equation
[tex]-3x + 5y = -25[/tex]
[tex]5y = 3x - 25[/tex]
[tex]y = \frac{3}{5}x - \frac{25}{5}[/tex]
[tex]y = \frac{3}{5}x - 5[/tex]
Substitute this value in the first equation
[tex]-8x - 7(\frac{3}{5}x - 5) = 96[/tex]
[tex]-8x - 7*\frac{3}{5}x + 7 * 5 = 96[/tex]
[tex]-8x - \frac{21}{5}x + 35 = 96[/tex]
Collect Like Terms
[tex]-8x - \frac{21}{5}x = 96 - 35[/tex]
[tex]\frac{-61}{5}x = 61[/tex]
[tex]x = 61 * \frac{-5}{61}[/tex]
[tex]x = -5[/tex]
Recall that
[tex]y = \frac{3}{5}x - 5[/tex]
This gives
[tex]y = \frac{3}{5} * -5 - 5[/tex]
[tex]y = -3 - 5[/tex]

Answer: Devon, Tasha, Liza, Effon
Step-by-step explanation:
From the question, we are informed that four friends race their bikes down the street and that Evan finishes in 6.2 seconds, Devon in 6.0999 seconds, Liza in 6.188 seconds, and Tasha in 6.168 seconds.
The order that shows the friends' times from fastest to slowest is:
• Devon
• Tasha
• Liza
• Effon
Devon used 6.0999 seconds which is the fastest time, after then Tasha comes next with 6.168 seconds, then Liza with 6.188 seconds and lastly Effon with 6.2 seconds

Number of Votes Cast for Each Candidate:
Candidate Votes
Candidate A 35

Candidate C 28
For every (blank)
votes cast for Candidate B, there were (blank )
votes cast for Candidate A.
Answer:
For every 7 votes cast for Candidate B, there were 5 votes cast for Candidate A.
Step-by-step explanation:
Given:
Candidate Votes
Candidate A 35
Candidate B 49
Candidate C 28
To find:
For every (blank) votes cast for Candidate B, there were (blank ) votes cast for Candidate A
Solution:
First we have to find the ratio of B and A
B : A
49 : 35
Now lets simplify the above ratio:
reduce the ratio using greatest common factor (GCF).
Use factorization method:
Write the numbers 35 and 49 as the product of their divisors.
The factors of 35 are: 1, 5, 7, 35
This means 35 is divided by 1, 5, 7 and 35 itself
The factors of 49 are: 1, 7, 49
This means 49 is divided by 1, 7 and 49 itself
Both have 7 common in them
Hence the greatest common factor is 7.
Next, divide both terms i.e. 35 and 49 by the greatest common factor, 7
49 / 7 = 7
35 / 7 = 5
The ratio 49 : 35 can be reduced to lowest terms by dividing both terms by the greatest common factor GCF = 7
So,
49 : 35 = 7 : 5
Hence
For every 7 votes cast for Candidate B, there were 5 votes cast for Candidate A.
