Solve. 14/n+7=10/n-4 N=5.25 N=3.5 N=31.5 N=30

Ilya [14]

Answer:

n=31.5

Step-by-step explanation:

The given question is:

$\frac{14}{n+7}=\frac{10}{n-4}$

Cross multiply to get:

$14(n-4)=10(n+7)$

Expand the parenthesis:

$14n-56=10n+70$

Group similar terms:

$14n-10n=70+56$

Combine the like terms

$4n=126$

Divide both sides by 4

$n=\frac{126}{4}$

n=31.5

Use the graph to answer the question. Find the slope

Liula [17]

We can take the two points given and plug them into the slope formula.

$\sf~m=\dfrac{y_2-y_1}{x_2-x_1}$

(-3, 3), (1, -5)
x1 y1 x2 y2

$\sf~m=\dfrac{-5-3}{1-(-3)}$

Subtract:

$\sf~m=\dfrac{-8}{4}$

Divide:

$\sf~m=-2$
