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

What is the slope of (-1,6) and (2,3)?
LenKa [72]

Answer:

-1

Step-by-step explanation:

For a line joining two points (x1, y1) and (x2, y2), it's slope is given as:

\boxed{ \mathsf{slope =  \frac{ y_{2} -y  _{1}}{ x_{2} - x _{1}} }}

Here, the two points are (-1, 6) and (2, 3) in place of (x1, y1) and (x2, y2).

Solving for slope:

\implies \mathsf{ \frac{3 - 6}{2 - ( -1 )} }

\implies \mathsf{ \frac{ - 3}{2  + 1 } }

\implies \mathsf{ \frac{ - 3}{3 } }

\implies \mathsf{  - 1 }

Hence, the slope of the line joining the given points is <u>-1.</u>
