Why doesn't a cube root have two answers

1 answer:

5 0

A cube root has THREE answers !

Unfortunately, two of them are 'complex' numbers, which involve
'imaginary' numbers', and those involve the square root of -1 .
In Middle School, you're not equipped to go there yet.

Just hang on for a few more years. You'll learn all kinds of
beautiful things in math, more than you can imagine now.
You'll learn that whatever number the root is, there are
THAT many answers.

Like for example, if you want the 7th root of a number,
there are seven of them !

Y/−7 = 1 /4 what does y =

Studentka2010 [4]

Answer:

4y = - 7 ( divide both sides by 4 )

y = - $\frac{7}{4}$

Graphing linear equations

ella [17]

Answer:

To ensure uniformity on an exam

To test whether you can distinguish between the two formats

Step-by-step explanation:

Standard form is when a straight line equation is rearranged in the form:

$ax + by = c$

Therefore y=2x+4 in standard form is

$2x - y = - 4$

The slope-intercept form is when a a straight line equation is written in the form:

$y = mx + c$

where m is the slope and c is the y-intercept.

The given equation is

$y = - \frac{1}{2} x - 5$

This is already in slope-intercept form:

The standard form and slope-intercept forms are just formats.

Your instructor may restrict you to leave your answer in one of these formats maybe for uniformity on a test.

You may also decide to rewrite an equation in slope-intercept form, so that you can easily identify the slope and y-intercept easily for graphing purpose.

Monica is a lawyer who earns $8,322.65 every month. She spends $830.98 on rent, $210.36 on food, and $120.45 on gas every month.

Step2247 [10]

She would have $7160.86 left over in cash here's why.....
she starts off with $8,322.65 and spends $830.98 on rent $8,322.65-$830.98= $7,491.67
then spends $210.36 on food and another $120.45 on gas
$7,491.67-$210.36= $7,281.31 - $120.45= $7,160.86 <---- Left over $

<span>Jane is playing a game with Mike. Right now, Mike is winning, he has 10 more than 5 times the points that Jane has. If Jane has 47 points, how many points does Mike have?

or you could do

</span><span>Martha is doing an inventory of all the goods in her shop. For the brand Toms shoes, she should have recieved an order that would have brought the total number of Toms shoes in her store to 10 more than 5 times the number of shoes she has now. If Martha has 89 pairs of Toms in her store, how many would she have had, if she had recieved the delivery?

hope this helped :)

What is -6n+5=1? Thanks!

ivann1987 [24]

You subtract 5 to the other side so it'll read -6n=-4 then divide -6 to the other side and it'll be 2/3
