Suppose that the functions r and s are defined for all real numbers x as follows. r(x) = 2x+4

s(x) = 6x

Write the expressions for (r-s)(x) and (r:s) (x) and evaluate (r+s)(-2).

(r - s) (x) = 1

x

?

(r+s) (-2)

Help me please

Ithink the answer is c

Solution: x2+4x=276x=27,x=9/2answer: no

1. use commutative property to reorder the terms.2x+81=0.2. move the constant to right side by adding its opposite on both sides. 2x+81-81=0-81.2x=(-81).3. divide the equation on both sides.2x ÷ 2 = 81 ÷ 2.x = -81/2. your answer is -81/2. if you need to simplify it into a decimal, it’s -40.5.
