I = sqrt(-1)
i^2 = -1
(-i)^2 = (-i)(-i) = i^2 = -1
(-i)^3 = (-i)(-i)(-i) = (-i)(i^2) = i
use these facts to find which equation is correct if x = -i
i bet on 2,3 or 4
There is an invisible +0 at the end. this means the y intercept is 0
Answer:
Step-by-step explanation:
y ÷ 3(4 - 2) + 5.5
= y ÷ 3(2) + 5.5
= y ÷ 6 + 5.5
= y/6 + 5.5
= (y + 33)/6
A. 1/2(140-100) = 20
X = 20
B. 4^2 = 3 (x+3)
16 = 3x + 9
X = 7/3
