Answer:

b = 2

Step-by-step explanation:

Using the midpoint formula

(2, 1) = [ \frac{1}{2}(- 4 + 8), \frac{1}{2}(b + 0) ]

considering the y-coordinate, then

\frac{1}{2} b = 1 ( multiply both sides by 2 )

⇒ b = 2

Simplify the expression given below.
trasher [3.6K]

Answer:

A) 1/(3x+1)

Step-by-step explanation:

(x+2)/(x³+2x²-9x-18)÷(3x+1)/(x²-9)

(x+2)/(x+2)(x+3)(x-3)÷(3x+1)/(x+3)(x-3)

since it’s dividing by a fraction, invert and multiply

(x+2)/(x+2)(x+3)(x-3) times (x+3)(x-3)/(3x+1)

The (x+2)’s cancel out.

The (x+3)’s cancel out.

The (x-3)’s cancel out.

You are left with 1/(3x+1)
