Write an equation of the line through the point (5, 3) that is perpendicular to the line –3x+7y=5.
Fed [463]

Answer:

7x + 3y = 44

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c (m is the slope and c the y- intercept )

Rearrange - 3x + 7y = 5 into this form by adding 3x to both sides

7y = 3x + 5 ( divide all terms by 7 )

y = \frac{3}{7} x + \frac{5}{7} ← in slope- intercept form

with slope m = \frac{3}{7}

Given a line with slope m then the slope of a line perpendicular to it is

m_{perpendicular} = - \frac{1}{m} = - \frac{1}{\frac{3}{7} } = - \frac{7}{3} , thus

y = - \frac{7}{3} x + c ← is the partial equation

To find c substitute (5, 3) into the partial equation

3 = - \frac{35}{3} + c ⇒ c = 3 + \frac{35}{3} = \frac{44}{3}

y = - \frac{7}{3} x + \frac{44}{3} ← in slope- intercept form

Multiply through by 3

3y = - 7x + 44 ( add 7x to both sides )

7x + 3y = 44 ← in standard form

Find the value of x in the given figure using properties of parallel lines.
marshall27 [118]

Answer:

x =42

Step-by-step explanation:

x and 138 are same side interior angles.  Same side interior angles are supplementary when the lines are parallel

x+138 = 180

x = 180-138

x =42
