Every Saturday, Justin gets an allowance of $10 from his parents. During every week since Justin began getting an allowance, he spends $8 and saves the remaining $2 of his allowance before he receives his next allowance. The sequence shown represents the amount of money Justin has right before and right after he gets his allowance for six consecutive weeks, starting with $0. 0, 10, 2, 12, 4, 14, 6, 16, 8, 18, 10, 20

Explain why this sequence is or is not a function?

A.

This sequence is not a function because the amount $10 appears in the sequence more than once.

B.

This sequence is not a function because the sequence does not form a line.

C.

This sequence is a function because each input (odd terms in sequence) maps to one output (even terms in sequence).

D.

This sequence is a function because each output (even terms in sequence) maps to one input (odd terms in sequence).
Thanks! I'm stuck between C, D and A

D. This sequence is a function because each output (even terms in sequence) maps to one input (odd terms in sequence).

Step-by-step explanation:

0, 10, 2, 12, 4, 14, 6, 16, 8, 18, 10, 20

he startes with $0 he gits his first allowance wich is $10, he spends $8 and saves $2. he gits anuther $10 and the remaning $2 is $12 he spends $8 he has $4 gits anuther $10 and the remaning $4 is $14 he spends $8 he has $6 he gits anuther $10 and the remaning $6 is $16 he spends $8 he has $8 he gits anuther $10 and the remaning $8 is $18 he spends $8 he has $10 he gits anuther $10 and the remaning $10 is $20.

hope this helped

step-by-step explanation: you take each of the numbers and divide by the amount then you take the range

answer: 75°

step-by-step explanation:

∠esk is the supplement of ∠edk, so is 100°. ∠esd = 1/2·arc ed, so is 25°.

since ∠esk = ∠esd + ∠dsk

you have 100° = 25° + ∠dsk . .

fill in known values 75° = ∠dsk . . . . .

subtract 25°
