When it asks this question, ultimately you want to plug 11 into x because its f(x). 11=-2+5.
Then you subtract 5 on both sides because of the opposite of addition is subtraction.
6=-2x
now divide on both sides
x=-3
C would be the answer. When you simplify the equations C does not contain a radical.
A^2 + 31 = 155 - I squared each of b and c for those numbers
a^2 = 155 - 31
a^2 = 124
a = 4 * sqrt(31)
1.2 8 x 15 percent = 8 x .15 = 1.2
M=-2/3
This is because it’s the slope I got and I don’t know how to explane it
