Solve the expression and find the value of x.

vovangra [49]

$\large\underline{\sf{Solution-}}$

$\sf \dfrac{x + 1}{10} - \dfrac{3(x - 1)}{5} = 2$

$\sf\longmapsto \dfrac{x + 1}{10} - \dfrac{3x - 3}{5} = 2$

$\sf\longmapsto \dfrac{(x + 1) - 2(3x - 3)}{10} = 2$

$\sf\longmapsto \dfrac{x + 1 - (6x - 6)}{10} = 2$

$\sf\longmapsto \dfrac{x + 1 - 6x + 6}{10} = 2$

$\sf\longmapsto \dfrac{ - 5x + 7}{10} = 2$

$\sf\longmapsto - 5x + 7 = 20$

$\sf\longmapsto - 5x = 20 - 7$

$\sf\longmapsto - 5x = 13$

$\sf\therefore x = - \dfrac{13}{5}$

Hence, the value of x will be -13/5 respectively.

Find the midpoint between (-1+9i) and B=(5-3i)

sdas [7]

Answer:

2 + 3i, midpoint is (2,3)

Step-by-step explanation:

we need to find the midpoint between (-1+9i) and B=(5-3i)

To find the midpoint of two points (a+bi) and (c+di) in a complex plane,

we apply formula

$\frac{a+c}{2} + \frac{b+d}{2} i$

A = (-1+9i) and B=(5-3i)

Midpoint for AB is

$\frac{-1+5}{2} + \frac{9+(-3)}{2}i$

$\frac{4}{2} + \frac{6}{2}i$

2 + 3i , so midpoint is (2,3)
