Please help me out...........

Answer 1

Answer:

N(c, b)

Step-by-step explanation:

If N is midpoint between Q and R, then use the formula of a midpoint:

$\left(\dfrac{x_1+x_2}{2},\ \dfrac{y_1+y_2}{2}\right)$

We have the points Q(0, 2b) and R(2c, 0). Substitute:

$x=\dfrac{0+2c}{2}=\dfrac{2c}{2}=c\\\\y=\dfrac{2b+0}{2}=\dfrac{2b}{2}=b$
