Find an equation of the line perpendicular to the graph of 14x-7=1 that passes through the point at (-2,4)

wolverine [178]

we know that

If two lines are perpendicular, then the product o their slopes is equal to minus one

$m1*m2=-1$

Step 1

<u>Find the slope of the given line</u>

we have

$14x-7=1\\14x=1+7$

$x=8/14$ -------> $x=4/7$

This line is parallel to the y-axis

the perpendicular will be parallel to the x-axis

Step 2

The equation of the line perpendicular to the given line is the y-coordinate of the given point

Point $(-2,4)$

the equation is

$y=4$

therefore

<u>the answer is</u>

$y=4$

see the attached figure to better understand the problem

-45b+5=67 what is the variable b

lisabon 2012 [21]

Answer:

$\large\boxed{b=-\dfrac{62}{45}}$

Step-by-step explanation:

$-45b+5=67\qquad\text{subtract 5 from both sides}\\\\-45b+5-5=67-5\\\\-45b=62\qquad\text{divide both sides by (-45)}\\\\\dfrac{-45b}{-45}=\dfrac{62}{-45}\\\\b=-\dfrac{62}{45}$

A printer can print 27 pages in 4.5 min. How much time does it need to print 324 pages?

lutik1710 [3]

Answer:

54 minutes

Step-by-step explanation:

We can write a proportion to solve this problem. Put the number of pages over the minutes

27 pages 324 pages

-------------- = ---------------

4.5 minutes x minutes

Using cross products

27 * x = 324 * 4.5

27x = 1458

Divide each side by 27

27x/27 = 1458/27

x =54
