Answer:

n = -2

Step-by-step explanation:

Eliminating parentheses, you have ...

2n +6 -6n = 14

Combining terms and subtracting 6, you get ...

-4n = 8

Dividing by the coefficient of n gives ...

n = -2

_____

<em><u>Check</u></em>

2(-2) +3(2 -2(-2)) = 14

-4 +3(2+4) = 14

-4 +3(6) = 14

-4 +18 = 14 . . . . answer checks OK

What is the solution of RootIndex 3 StartRoot x + 8 EndRoot = negative 4?

erica [24]

Answer: First option.

Step-by-step explanation:

Given the following equation provided in the exercise:

$\sqrt[3]{x+8}=-4$

You can follow the steps indicated below in order to find the solution of this equation:

1. Cubing both sides of the equation, you get:

$(\sqrt[3]{x+8})^3=(-4)^3\\\\x+8=-64$

2. Finally you must subtract 8 from both sides of the equation:

$x+8-8=-64-8\\\\x=-72$

You can notice that this solution matches with the first option.

What is the inverse of the function g(x)=-\dfrac{2}{3}x-5g(x)=− 3 2 x−5g, left parenthesis, x, right parenthesis, equals, minu

Semenov [28]

Answer:

$g^{-1}(x)=-\frac{3}{2}x-\frac{15}{2}$

Step-by-step explanation:

Given function,

$g(x) = -\frac{2}{3}x-5$

Step 1 : Replace g(x) by y:

$y = -\frac{2}{3}x-5$

Step 2 : Swap x and y:

$x = -\frac{2}{3}y-5$

Step 3 : Solve the equation for y ( isolate y in the left side ):

$x +\frac{2}{3}y=-5$

$\frac{2}{3}y=-5-x$

$y=\frac{3}{2}(-5-x)$

$y=-\frac{15}{2}-\frac{3}{2}x$

$y=-\frac{3}{2}x-\frac{15}{2}$

Step 4: Replace y by $g^{-1}(x)$ :

$g^{-1}(x)=-\frac{3}{2}x-\frac{15}{2}$

Hence, the inverse of the function g(x) is $g^{-1}(x)=-\frac{3}{2}x-\frac{15}{2}$ .

What is the value of g if g = 8.8? 72g = ?

Sidana [21]

If g = 8,8 so than 72g = 72*8,8 = 633,6

hope i understand it right

bc. << what is the value of g if g = 8,8 ? >> so this is something missed bc. i think when the value of g is given so than not can being asked what is the value of g ????

Write the slope intercept form of the equation of the line through the given points and slope 1,1 and slope of -3/5

Maslowich

Slope is already given in the question so we only need to solve for the y-intercept.

Slope intercept form: y = mx + b

m = slope

b = y-intercept

-3/5 = -0.6

1 = -0.6(1) + b

1 = -0.6 + b

1 + 0.6 = -0.6 + b + 0.6

1.6 = b

Now, write in slope-intercept form.

y = -3/5x - 1.6
