Answer:
x=18
Step-by-step explanation:
Key skills needed: Arithmetic Sequences, Addition
1) We have a sequence of 8,13,x
2) To find the number being added every time, we do 13-8. This is 5.
3) This means x would be 13+5
4) 13+5 is 18 so x is 18.
Hope you understood and have a nice day!! :D

If (3a + 3b + 1) (3a + 3b - 1) = 80, then what is a + b?
Answer: a + b = 3 - maybe
Step-by-step explanation:
( 3a + 3b + 1 )( 3a + 3b - 1 ) = 80
Expand
9a² + 9ab - 3a + 9ab + 9b² - 3b + 3a + 3b - 1 = 80
Simplify
9a² + 9b² + 18ab - 1 = 80
move the 1 over
9a² + 9b² + 18ab = 81
divide by 9
a² + b² + 2ab = 9
not really sure after this part
move the 2ab over
a² + b² = 9 - 2ab
square root both sides
a + b =
simplify
a + b = 3 -

Solve the system of linear equations by elimination.
9x+y=2
−4x−y=−17
Answer: x = -3 y = 29
Step-by-step explanation:
9x + y = 2
-4x - y = -17
5x = -15
Divide both sides by 5
x = -3
9x + y = 2
Substitute -3 for x
9 (-3) + y = 2
-27 + y = 2
Add 27 to both sides
y = 29

Please write a Equation for the Line.
Step-by-step explanation:
Hey there!
The given points are; (1,-3) and (3,1).
Note: Use double point formula.
[tex](y - y1) = \frac{y2 - y1}{x2 - x1} (x - x1)[/tex]
~ Put all values.
[tex](y + 3) = \frac{ - 1 - 3}{3 - 1} (x - 1)[/tex]
~ Simplify it.
[tex]y + 3 = - 2x + 2[/tex]
[tex]2x + y + 1 = 0[/tex]
Therefore, the eqaution is; 2x+y+1= 0.
Hope it helps....

The first 5 terms of a linear sequence are shown above.
What is the 100th term in the sequence?
9514 1404 393
Answer:
-190
Step-by-step explanation:
The n-th term of an arithmetic (linear) sequence is given by ...
an = a1 +d(n -1)
where a1 is the first term (8) and d is the common difference. We note that each term is 2 less than the one before, so the common difference is -2.
an = 8 -2(n -1)
Then the 100th term is ...
a100 = 8 - 2(100 -1) = 8 -198 = -190
The 100th term is -190.
