Find the slope of the line that is perpendicular to the line that passes through the points (5,2) and (8,1)
Naya [18.7K]

Answer:

3

Step-by-step explanation:

The slope of the line passing through the points is

m = (y2-y1)/(x2-x1)

    = ( 1-2)/(8-5)

   = -1/3

The slope that is perpendicular is the negative reciprocal which is

- ( 1/(-1/3)

+ 3/1

The perpendicular slope is 3

LOTS OF POINTS <br> Simplify the expression by factoring, showing the steps in your work
julia-pushkina [17]

Answer:

\frac{3x+7}{4x+1}

Step-by-step explanation:

\frac{12x^2+31x+7}{16x^2+8x+1}

First you factor 12x^2+31x+7:

=\left(12x^2+3x\right)+\left(28x+7\right)

Then you factor out 3x from 12x^2+3x:

12x^2+3x

=12xx+3x

=3\cdot \:4xx+3x

=3x\left(4x+1\right)

Then you factor out 7 from 28x+7:

28x+7

=7\cdot \:4x+7

=7\left(4x+1\right)

=3x\left(4x+1\right)+7\left(4x+1\right)

Factor out common term 4x+1:

=\left(4x+1\right)\left(3x+7\right)

\frac{\left(4x+1\right)\left(3x+7\right)}{16x^2+8x+1}

Factor 16x^2+8x+1:

=4^2x^2+8x+1

=4^2x^2+8x+1^2

=\left(4x\right)^2+8x+1^2

=\left(4x\right)^2+2\cdot \:4x\cdot \:1+1^2

Use the perfect square formula:

=\left(4x+1\right)^2

\frac{\left(4x+1\right)\left(3x+7\right)}{\left(4x+1\right)^2}

Cancel out common factor 4x+1:

=\frac{3x+7}{4x+1}
