2 and 4. In equations where the line is parallel, the slope is the same. By eyeing this number 2 is right but number four is right as well because when you put y by itself and divide the 2 from the whole equation, it is ultimately the same and still parallel from the original equation.
The angles x and 55.1 degrees are COMPLEMENTARY ANGLES. Please look up that term if necessary.
Subtract the angle 55.1 degrees from ( what? ) to obtain angle x.
F^-1(x) is the inverse so...
f^-1(x) = (-1/5)x - 11/5
Whenever there is no exponent on a variable,
you can give it an exponent of 1.
So we can rewrite the x's in this problem as x¹.
When we multiply two terms together
with like bases, we add their exponents.
So now just add their exponents to get x².
