If (2i/2+i)-(3i/3+i)=a+bi, then b=

max2010maxim [7]

Answer:

b = -1/10.

Step-by-step explanation:

(2i/2+i)-(3i/3+i)

= 2i(3 + i) - 3i(2 + i) / (2 + i)(3 + i)

= 6i + 2i^2 - 6i - 3i^2 / (2 + i)(3 + i)

= (-2 + 3) / (6 + 5i - 1)

= 1 / (5 + 5i)

Now we multiply top and bottom by 5 - 5i :

= 5 - 5i / (5 + 5i)(5 - 5i)

= 5 - 5i / 25 -25i^2

= 5 - 5i / 50

= 1/10 - 1/10i

larisa [96]

Answer:

Step-by-step explanation:

Given

$240 = 12x + 8y$

Required

Plot a graph

First, we need to determine the minimum and maximum values of x and y

For x:

Minimum = 0

For maximum; Let y = 0

$240 = 12x + 8y$

$240 = 12x + 8 * 0$

$240 = 12x$

Solve for x

$x = 240/12$

$x = 20$

For y:

Minimum = 0

For maximum; Let x = 0

$240 = 12x + 8y$

$240 = 12 * 0 + 8 * y$

$240 = 8y$

Solve for y

$x = 240/8$

$x = 30$

Write the sum, and then write an equivalent expression by collecting like terms and removing parentheses whenever possible.

Yanka [14]

Answer:

The sum is $t$ .

Step-by-step explanation:

Consider the provided information.

The given expression are - 10t and t - 10t

We need to find the sum of the opposite of -10 t and t - 10t.

The opposite of -10 t is 10 t.

$10t+(t-10t)$

Remove the parenthesis.

$10t+t-10t$

Simplify the number

$10t-10t+t$

Use Additive inverse.

$t$

Hence, the sum is $t$ .
