Factor out cosx: cosx(sinx-2)=0
cosx=0 or sinx-2=0
cosx=0 or sinx=2
the largest value of sinx is 1, sinx will never be 2, so cosx=0, x=π/2 or 3π/2 are the two answers.

Find the midpoint M of the line segment joining the points P= (-7,-8) and Q = (3,2)
Fed [463]

Answer:

(-2, -3)

Step-by-step explanation:

To solve this problem, we use the midpoint formula.

M = \frac{x1 + x2}{2} , \frac{y1+ y2}{2}

Plug your coordinates in:

M = \frac{-7 + 3}{2} , \frac{-8 + 2}{2}

Simplify:

M = \frac{-4}{2} , \frac{-6}{2}

M = (-2,-3)
