(-19+7i)-(29+32i)=<br><br> in the form (a+bi)

olga_2 [115]

ANSWER

$-48-25i$

EXPLANATION

We want to simplify the expression,

$(-19+7i) - (29+32i)$

Let us expand the bracket to obtain,

$-19+7i-29-32i$

We now group the complex number parts and real number parts.

$-19 -29+7i-32i$

We simplify further to obtain,

$- 48-25i$

This is in the form,

$a+bi$

where

$a=-48$

and

$b=-25$

What is<br> is 1/4 + 9/10y -3/5y +7/8 written in simplest form?

Leviafan [203]

Answer:

Step-by-step explanation:

$\frac{1}{4}+\frac{9}{10}y - \frac{3}{5}y+\frac{7}{8}\\\\=\frac{1}{4}+\frac{7}{8}+\frac{9}{10}y-\frac{3}{5}y\\\\$

Combine like terms. 1/4 and 7/8 are like terms and LCD of 4 and 8 is 8

9/10y and -3/5y are like terms and LCD of 10 , 5 is 10

$= \frac{1*2}{4*2}+\frac{7}{8}+\frac{9}{10}y-\frac{3*2}{5*2}y\\\\=\frac{2}{8}+\frac{7}{8}+\frac{9}{10}y-\frac{6}{10}y\\\\=\frac{9}{8}+\frac{3}{10}y$
