Rearrange the equation so nnn is the independent variable. m+1=-2(n+6)m+1=−2(n+6)

Answer:

m=-2n-13

Step-by-step explanation:

The given equation is m+1=-2(n+6)

We want to rearrange this equation so that, n becomes the  independent variable.

This means we must solve form, m which becomes the dependent variable.

We expand the parenthesis to get:

m+1=-2n-12

We now subtract 1 from both sides to obtain:

m=-2n-12-1

We simplify to obtain:

m=-2n-13

This can be rewritten as

m(n)=-2n-13

Answer:

5.8

Step-by-step explanation:

Side KI is proportional to HF, and as we know GH is proportional to JK, we can make a proportion. x/31 = 8/43, 43x = 248, so x = 5.767, which rounds to 5.8

Simplify. Assume that no denominator is equal to zero. ([3^2]^3g^3h^4)^2
mariarad [96]

Answer:

531,441·g^6·h^8

Step-by-step explanation:

The operative rule of exponents is ...

(a^b)^c = a^(b·c)

Working from the inside out, according to the order of operations, we get ...

= (9^3·g^3·h^4)^2

= 729^2·g^(3·2)·h^(4·2)

= 531,441·g^6·h^8

10 men working for 6 days can complete 5 copies of a book if there are 8 men working to complete 4 copies of the book how many d
Musya8 [376]

Answer:

6 Days

Step-by-step explanation:

Practically:

It takes,

10 Men ( complete ) 5 Copies --> 6 Days

So, 2 Men can complete 1 copy in 6 days.

Question asks us :

8 Men ( complete ) 4 Copies --> X Days

It will take 6 days because the proportion of men to copies is same as the first equation.

Theoretically:

10 Men 5 Copies 6 Days

8 Men   4 Copies  X Days

> 6/X = 8/10 ( If men decrease the number of days increase. So, it is an indirect proportion. ) . 5/4 ( If copies decrease the number of days decrease as well. So, it is a direct proportion. )

> 6/X = 8/10 . 5/4

> 6/X = 40/40

> 6/X = 1

<h2>> X=6</h2><h2></h2><h2><em>I hope it will be understood.</em></h2><h2><em>If I have any inaccuracies please let me know.</em></h2><h2><em>Have a nice day and never stop questioning!</em></h2><h3><em></em></h3>

Help me on number problem 4 please
kakasveta [241]

Answer:

y = -1/4x + 3

Step-by-step explanation:

Because you are finding the perpendicular slope, you need to find the negative reciprocal of the original line, which would be -1/4. You then use point slope form to find the y-intercept with the slope and given point:

y - 5 = -1/4(x + 8). That equals to y = -1/4x + 3.

So the equation of this line is y = -1/4x + 3.
