Write the equation of the line that is perpendicular to 3x + 7y = 15 and passes through (4, 9)

k0ka [10]

Answer:

7x - 3y = 1

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 = 15 into this form

Subtract 3x from both sides

7y = - 3x + 15 ( divide all terms by 7 )

y = - $\frac{3}{7}$ x + $\frac{15}{7}$ ← in slope- intercept form

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

Given a line with slope m the 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 of the line

To find c substitute (4, 9) into the partial equation

9 = $\frac{28}{3}$ + c ⇒ c - $\frac{1}{3}$

y = $\frac{7}{3}$ x - $\frac{1}{3}$ ← in slope- intercept form

Multiply through by 3

3y = 7x - 1 ( subtract 3y from both sides )

0 = 7x - 3y - 1 ( add 1 to both sides )

1 = 7x - 3y, that is

7x - 3y = 1 ← in standard form

Someone please help Evaluate the formula V= Bh/3 for B= 15in ^2 And H=28in

White raven [17]

Answer:

$\large\boxed{V=140\ in^3}$

Step-by-step explanation:

$V=\dfrac{Bh}{3}\to\text{it's a formula of a volume of a pyramid or a cone}\\\\B-base\ area\\h-height\\\\\text{We have}\ B=15\ in^2\ \text{and}\ h=28\ in.\\\\\text{Put the given values to the formula of a volume:}\\\\V=\dfrac{(15)(28)}{3}=(5)(28)=140\ in^3$
