Suppose that the functions r and s are defined for all real numbers x as follows. r (x)=2x-6
s(x) = 6x
Write the expressions for (r-s)(x) and (r+s)(x) and evaluate (r-s)(2).

more detail

step-by-step explanation:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

4y - 6 + y^2 - 9 = y^2 + 4y - 15

y^2 term

- terms

total of 3 terms when simplified
