Answer:
(x) = 2x + 12
Step-by-step explanation:
let y = f(x) and rearrange making x the subject
y = x - 6 ( multiply through by 2 to clear the fraction )
2y = x - 12 ( add 12 to both sides )
2y + 12 = x
change y back into terms of x with x = (x) , then
(x) = 2x + 12
Answer:
D
Step-by-step explanation:
To be a solution, the number must be less than -8. This means it is located to the left of -8 on the number line.
Only -10 is to the left of -8 and less than it.

Answer: 18</h3>
Reason:
Subtract any pair of adjacent terms
- d = term2 - term1 = -74 - (-92) = -74+92 = 18
- d = term3 - term2 = -56- (-74) = -56+74= 18
- d = term4 - term3 = -38- (-56) = -38+56= 18
- d = term5 - term4 = -20- (-38) = -20+38= 18
Each time we get the same value to confirm that we have an arithmetic sequence of common difference 18.
