Answer:
(n + 1)²
Step-by-step explanation:
note that 4, 9, 16, 25, 36 are square numbers
To generate the terms add 1 to the position n and square, that is
first term : n = 1 → n = 1 + 1 → 2² = 4
second term : n = 2 → n = 2 + 1 → 3² = 9
third term : n = 3 → n = 3 + 1 → 4² = 16
Hence n th term is (n + 1)²
Multiply each hourly rate by x ( time to complete the work) add it to the service call for each and then set the equations equal:
50 + 40x = 30 +45x
Subtract 30 from both sides:
20 + 40x = 45x
Subtract 40x from both sides:
20 = 5x
Divide both sides by 5
x = 4
The length is 4 hours.
Answer:

Hello from MrBillDoesMath!
Answer: f(x) = (2/3)*x -3 -- which is not a provided answer..
Discussion:
We are given that y + 7 = (2/3) * (x + 6). Multiply out the right hand side:
y + 7 = (2/3) * x + (2/3) * 6 = (2/3) *x + 12/3
= (2/3)*x + 4
Subtract 7 from both sides:
y + 7 - 7 = (2/3)*x + 4 - 7
or
y = (2/3)*x -3
Thank you,
MrB
y + 7= 2/3(x+6)
