Rearrange the equation so u is the independent variable 4u + 8w = -3u + 2w

please please help !! will mark brainliest if correct

on khan academy. if you are unable to solve this, this is function rules from equations on 8th grade !!!

w = -7/6 u

Step-by-step explanation:

The independent variable is in the equation, we solve for the dependent variable

So we solve for w

4u + 8w = -3u + 2w

Subtract 2w from each side

4u + 8w-2w = -3u + 2w-2w

4u+6w = -3u

Subtract 4u from each side

6w = -3u-4u

6w = -7u

Divide by 6

6w/6 = -7u/6

w = -7/6 u

Step-by-step explanation:

geometric series converge the common ratio r has magnitude less than one.

which is equivalent to

for the example we need

|2-x| < 1

-1 < 2-x   and 2-x < 1

x < 3 and x > 1

we can write that

answer: 1 < x < 3

1a. common ratio r=250/25=10 > 1     diverges

1b.   r=50/100=1/2 converges

when these converge they converge to

where a is the first term.

answer: 200

1c. r=-1   so it's not the case that |r| < 1.     diverges

2a. x is the common ratio so we converge when |x|< 1

2b.   r=-10x / -2 = 5x.

we converge when

|5x| < 1

|x| < 1/5

2c.   r=3-2x

-1 < 3-2x and 3-2x < 1

-4 < -2x and 2 < 2x

x < 2 and 1 < x

1 < x < 2

2d. [/tex] r=-48x^3/12 = 4x^3[/tex]

|4x^3| < 1

|x^3| < \frac 1 4

|x| < 4^{-1/3}

step-by-step explanation:

well if you round, things become much more simple. round 5.95 to 6, 4.25 to 4, and 1.05 to 1. now, add 6+4+1 and that would equal 11. so the items together would equal to about $11.
