Find the first four iterates of the function f(z) = 22 - 2 - 21 with an initial value of 20 = 2+1
a. 1+2i, 2 - 51, - 125 - 221, 191
b. 1+2i, - 5+ 21, 19-221, – 125 – 838
c. 1+2i, - 5+2i, 19-221, - 125 + 1
d. 2+1, 1+ 21, 2 - 221

The value of x in this system of equations is 1. 3x + y = 9 y = –4x + 10 substitute the value of y in the first equation: combine like terms: apply the subtraction property of equality: apply the division property of equality: 3x + (–4x + 10) = 9 –x + 10 = 9 –x = –1 x = 1 what is the value of y?
