Which equation represents a nonlinear function? x(y – 5) = 2
y – 2(x + 9) = 0
3y + 6(2 – x) = 5
2(y + x) = 0

x(y – 5) = 2

Step-by-step explanation:

Divide each side by x:

[x(y – 5)] / x  = 2/x

→  y – 5 = 2/x

Add 5 to each side of the equation:

y – 5 + 5 = 2/x + 5

→  y = 2/x + 5  ;  not a line;  since one cannot divide by zero ; there would be no point on the graph at x = 0.

this is the formula: v = the value of investment at the end of the time period

p = the principal amount (the initial amount invested)

r = the annual interest rate

n = the annual frequency of compounding (how many times a year interest is added)

t = the number of years the money is invested
