Find the coordinates of point which divides the line segment joining the points (a+b,a-b) and (a-b,a+b) in the ratio 3:2 interal

sasho [114]

Answer:

Coordinate of 0 = $\bigg( \dfrac{5a-b}{5},\:\dfrac{5a+b}{5}\bigg)$

Step-by-step explanation:

Let AOB be the line segment
Point 'O' divides the line segment into m:n = 3:2

Given:

Coordinate of a = (a+b, a-b)
Coordinate of b = (a-b, a+b)
Ratio = 3:2

ToFind:

Coordinate of 0 (zero)

Solution:

ATQ,

$\dfrac{m}{n}=\dfrac{3}{2}$
Coordinate of a = (x $_{1}$ , y $_{1}$ )
Coordinate of b = (x $_{2}$ , y $_{2}$ )

As we know that,

$\implies\:\:x = \dfrac{mx_{2} + nx_{1}}{m + n}$

$\implies\:\:x = \dfrac{(a-b)3 + (a+b)2}{3+2}$

$\implies\:\:x = \dfrac{3a - 3b + 2a + 2b}{5}$

$\implies\:\:\red{x = \dfrac{5a - b}{5}}$

Similarly,

$\implies\:\:y = \dfrac{my_{2}+ny_{1}}{m+n}$

$\implies\:\:y = \dfrac{(a+b)3+(a-b)2}{3+2}$

$\implies\:\:y = \dfrac{3a+3b+2a-2b}{5}$

$\implies\:\:\red{y = \dfrac{5a+b}{5}}$

Hence,

Coordinate of 0 is $\blue{\bigg( \dfrac{5a-b}{5},\:\dfrac{5a+b}{5}\bigg)}$

So find the area of the WHOLE triangle shaded or not, and use the formula 1/2bh. After that, use the same formula to find the area of the non shaded triangle. Then, subtract the non shaded from the big traingle. Hope I helped! :)

How can 7 1/5+(-8 3/5) be expressed as the sum of its integer and fractional parts

Nadya [2.5K]

Answer:

see the explanation

Step-by-step explanation:

we know that

A mixed number is the sum of a integer and a fractional part

we have

$7\frac{1}{5}+(-8\frac{3}{5})$

$7\frac{1}{5}=7+\frac{1}{5}$

$-8\frac{3}{5}=-8-\frac{3}{5}$

substitute

$7+\frac{1}{5}+(-8-\frac{3}{5})$

Group terms

$(7-8)+(\frac{1}{5}-\frac{3}{5})$

$(-1)+(-\frac{2}{5})$

$-1\frac{2}{5}$
