Is the given value a solution to the equation? 4(n) - 3 = -2(n) + 9 n=2

nlexa [21]

Answer:

Yes!

The solution to the equation is n = 2

Step-by-step explanation:

Given the equation

$4\left(n\right)-3=-2\left(n\right)+9$

remove the parentheses

$4n-3=-2n+9$

Add 3 to both sides

$4n-3+3=-2n+9+3$

Simplify

$4n=-2n+12$

Add 2n to both sides

$4n+2n=-2n+12+2n$

Simplify

$6n=12$

Divide both sides by 6

$\frac{6n}{6}=\frac{12}{6}$

Simplify

$n=2$

Therefore, the value of n = 2.

Hence,

Yes!

The solution to the equation is n = 2

Find the equation of the line passing through the points (-2/3,1) and (-2,1/2). Write the equation in standard form.

7nadin3 [17]

Standard form is y = mx + b.
To find the slope, m, we must find the 'rise over run,' or the difference in y divided by the difference in x. We do this by:
$\frac{y1 - y2}{x1 - x2} = \frac{ (- \frac{2}{3} ) - ( -2 )}{(1) - ( \frac{1}{2} ) } = \frac{ \frac{4}{3} }{ \frac{1}{2} } \\ = \frac{4}{3} \times \frac{2}{1} = \frac{8}{3}$
Therefore, the slope is 8/3.

To find b, we must plug in the slope and one point:
$(1) = ( \frac{8}{3} )( - \frac{2}{3} ) + b \\ 1 = - \frac{16}{9} + b \\ \frac{25}{9} = b$
Therefore, b is 25/9, and the total equation is
$y = \frac{8}{3} x + \frac{25}{9}$
