Answer: the first one -2+5i
Step-by-step explanation: because if we just take out the parenthesis the we can do it like a regular equation so 6-8 is -2 and 2i - -3i the 2 negatives gives us a positive so we get 2i+3i and get 5i so the equation would be -2+5i
42% of 100 is 42 so 42% of is half of the first answer, therefore the answer is 21.
It would be option 2 because -3 is the lowest value and y=Mx+b b is the y intercept
Y = -1/3x + 6 . . . (1)
x = -6 . . . (2)
Putting (2) into (1), gives
y = -1/3(-6) + 6 = 2 + 6 = 8
Solution is (-6, 8)
