Kaileys bank account balance was -$65.12 at the end of july. in september, the size of her debt increased by $21.55. she wants her bank account to have a balance of zero by the end of november. how much will kailey have to make?

answer: a and c are correct

step-by-step explanation:

the +5 is the vertical translation

the added negative symbol in front is the reflection over the y-axis

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
