The formular which can be used to obtain the monthly charges as a function of the number of cheques written is 9.75 + 0.15x
Charges on account :
- Charge per check written = $0.15
- Monthly services charge = $9.75
The total amount charged monthly, F as a function of the number of cheques written, x can be expressed thus :
Monthly service charge + (charge per check × number of cheques written)
F(x) = 9.75 + 0.15x
Therefore, the charge function which can be used to calculate the total monthly charge on his account ls F(x) = 9.75 + 0.15x

Answer: A) (2+2) x 3
Step-by-step explanation: The answer to the problem (2 X 3) + (2 X 3) is 12 so we have to find the eqaution in the answers that equals 12,
B) 2 + (3+3) is equal to 8 so that can't be the correct answer
C) 2 x 3 x 3 is equal to 18 so that can't be the correct answer
D) (2 + 3) x (3+2) simplifies to 5 x 5 which is 25 so that can't be the correct answer
So that leaves us with A) (2+2) x 3 as the correct answer because it equals <u>12</u>
3y=-6x-1
y=-2x-1/3 is the answer
The zero of a function is the x-value where the function crosses the x-axis. With a graph, it is easier often to just look at where the function crosses the x-axis instead of calculating it mathematically.
