6 ≤ 5(x - 4) -2(-x + 1)
First, distribute 5 to all terms within the first parenthesis, and -2 to all terms in the second parenthesis
6 ≤ (5x - 20 + 2x -2)
Combine like terms
6 ≤ (5x + 2x - 20 - 2)
6 ≤ 7x - 22
Isolate the x. Do the opposite of PEMDAS. Note that what you do to one side you to the other.
Add 22 to both sides
6 (+22) ≤ 7x - 22 (+22)
28 ≤ 7x
Divide 7 from both sides
28/7 ≤ 7x/7
28/7 ≤ x
4 ≤ x is your answer
Use a closed dot (because of the equal underneath) on 4, and go left with an arrow

Answer:
n = 4
Step-by-step explanation:
4(2n + 3) = 44
Expand the brackets.
4(2n) + 4(3) = 44
8n + 12 = 44
Subtract 12 on both sides.
8n + 12 - 12 = 44 - 12
8n = 32
Divide both sides by 8.
(8n)/8 = 32/8
n = 4
The answer is 1 bc the solution is (1,-3)
This is what we call a Fibonacci sequence:
Notice that after the 1,1:
4th term =3 ==> 2+1
5th term =5 ==>3+2
6th term =8==> 5+3
7th term = 13==> 8+5
8th term =...........13+8 =21
9th term = ...........21+13 =34
10t=h term =........34+21 = 55
In short each number equal the sum of the 2 preceding number
It’s not a function because there are two y values for the same x value at x=2
