M=p/n+4 make n the subject

Kipish [7]

Answer:

$n = \frac {p - 4m}{m}$

Step-by-step explanation:

Given the algebraic expression;

$m = \frac {p}{n + 4}$

To make n the subject of formula.

Cross-multiplying, we have;

$m*(n+4) = p$

$mn + 4m = p$

Rearranging the equation, we have;

$mn = p - 4m$

$n = \frac {p - 4m}{m}$

Write an equation of the line that passes through the given points. (-1,5) and (2, - 7)

Vanyuwa [196]

Answer:

The equation of the straight line is 4x +y = 1

Step-by-step explanation:

Step(i):-

Given points are (-1,5) and ( 2,-7)

Slope of the line

$m =\frac{y_{2}-y_{1} }{x_{2} -x_{1} } =\frac{-7-5}{2-(-1)} = \frac{-12}{3} = -4$

slope of the line m = -4

Step(ii):-

The equation of the straight line passing through the point (-1,5) and having slope 'm' = -4

$y - y_{1} = m( x-x_{1} )$

y - 5 = -4 ( x-(-1))

y -5 = -4 x -4

4 x + y -5 +4=0

4x +y -1 =0

Final answer:-

The equation of the straight line is 4x +y = 1
