Answer:
an arithmetic sequence or a linear function.
Step-by-step explanation:
<h2>
Arithmetic:</h2>
he has $100 and ADDS $20 each month. in arithmetic sequences we have a value for a sub 1 in this case 100, then add the rate of change or in this case 20 times the months or d. Since this function follows the rules this is an arithmetic sequence.
<h2>
Linear function:</h2>
y=mx+c
let y be the amount of money he has in his banking account,
let x be months.
let m be 20 because that is what he adds per month or per x.
let c be the starting value or 100.
y=20x+100
Let Craig's Saving =$ x
104 is the product of Craig’s savings and 8
A.T.Q
Writing the statement in Expression form
⇒
⇒

So, Craig saving=$ 13
Amount saved by Craig=$13
For 4 4 to 5 16 to 20 24 to 30
9 < = 6 - y
9 - 6 < = -y
3 < = -y
-3 > = y or y < = -3
solutions include : -3,-4,-6
Im not sure but i think its A because you have no value to multiply 3 so you just multiply it by itself.It would be a negative because you cant divide 3 by 2.so it would be A.-x9y2.
i hope i was correct and helped if not you can go ahead and delete my answer:)
