F(x+1) = f(x) + 2.5 with f(x) is the current number.
Equation: 21+n=43.23
Process to find n
21+n=43.23
Subtract 21 from both sides
n=22.23

Answer:
Domain: input values, independent variables
Range: output vales, dependent variables
Step-by-step explanation:
Think of it like a graph: the domain are the x-values and the range is the y-values. if you're doing a problem with time, the time will go on the x-axis and cannot be influenced by the y-values, but the y-vales are depending on what the x-values are (independent/dependent). for the input/output, usually when solving equations on a graph, you plug in the x-value and find the y-value. you're INPUTTING the x-value to receive the OUPUT.
Answer:
1/4 - (2/5 + (1/3 - (3 - 7/2) - 1/4) - 2/15)
= 1/4 - (2/5 + (1/3 - (6/2 - 7/2) - 1/4) - 2/15)
= 1/4 - (2/5 + (1/3 - (-1/2) - 1/4) - 2/15)
= 1/4 - (2/5 + (1/3 + 1/2 - 1/4) - 2/15)
= 1/4 - (2/5 + (4/12 + 6/12 - 3/12) - 2/15)
= 1/4 - (2/5 + (7/12) - 2/15)
= 1/4 - (2/5 + 7/12 - 2/15)
= 1/4 - (24/60 + 35/60 - 8/60)
= 1/4 - (51/60)
= 15/60 - 51/60
= -36/60
= -3/5
