Answer:
C.
Step-by-step explanation:
A complementary angle is an angle at 90 degrees and is formed by 2 angles.
Answer:
B
Step-by-step explanation:
y = 4 is a horizontal line parallel to the x- axis
A parallel line must also be horizontal with equation
y = c ( c is the value of the y- coordinates the line passes through )
The only equation in this form is
y = 0 ( the equation of the x- axis ) → B
Y = (x - 6)/4
to find the inverse of a function, you swap the x and y variables, then solve for y.
y = (x - 6)/4 ... swap x and y
x = (y - 6)/4 ... solve for y, start by multiplying both sides by 4 to cancel out your denominator
4x = (y - 6) ... add 6 to both sides
4x + 6 = y
your inverse function is y = 4x + 6
