Answer 1

Answer:

Step-by-step explanation:

A(-7,2) ; C(3 , -2)

m:n = 3: 1

$B(x_{1},y_{1})=(\frac{mx_{2}+nx_{1}}{m + n},\frac{my_{2}+ny_{1}}{m + n})\\\\\=(\frac{3*3+1*[-7]}{3+1} ,\frac{3*[-2]+1*2}{3+1})\\\\\\=(\frac{9-7}{4} ,\frac{-6+2}{4})\\\\\\=(\frac{2}{4} ,\frac{-4}{4})\\\\\\=(\frac{1}{2} ,-1)\\\\=(0.5 , -1)$
