from 1200 to 850, 1200 - 850 = 350.

if we take the 1200 to be the 100%, what is 350 off of it in percentage?

\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} 1200&100\\ 350&x \end{array}\implies \cfrac{1200}{350}=\cfrac{100}{x}\implies \cfrac{24}{7}=\cfrac{100}{x} \\\\\\ 24x=700\implies x=\cfrac{700}{24}\implies x = \cfrac{175}{6}\implies x = 29.1\overline{6}

If A and B are two points having coordinates (- 2, 2) and (2,-4) respectively, find the coordinates of P such that AP= AB.​
Karo-lina-s [1.5K]

Answer:

(0,1)

Step-by-step explanation:

The mid point of A(-2,2) and B(2,-4) is the coordinates of point P, which is (x,y)

Hence, the line AB = AP + PB.

At point AP: x = (-2+2)/2 = 0

also, point PB: y = (2 - 4)/2 = -1

Therefore, coordinates of point P = (0,-1)
