Given line y-1/6x+9,find a perpendicular line to the given line passes through points (6,-3)?
DerKrebs [107]

Answer:

y + 3 = (6)(x - 6)

Step-by-step explanation:

The proper format for this equation y-1/6x+9 is y = (-1/6)x+9.

Any line perpendicular to y = (-1/6)x+9 has the slope which is the negative reciprocal of that of y = (-1/6)x+9, or the negative reciprocal of -1/6.  That is +6.  

Thus, the desired line, which passes through (6, -3), is found using the point-slope formula for the equation of a straight line:

y + 3 = (6)(x - 6)

How do I solve for x
skad [1K]

Answer:

<h3>x = 40/7</h3>

Step-by-step explanation:

Look at the picture.

If ABC is any triangle and AD bisects (cuts in half) the angle BAC, then

\dfrac{AB}{BD}=\dfrac{AC}{DC}

In our triangle we have the proportion:

\dfrac{x}{8}=\dfrac{10-x}{6}            <em>cross multiply</em>

6x=8(10-x)               <em>use distributive property</em>

6x=(8)(10)+(8)(-x)

6x=80-8x                   <em>add 8x to both sides</em>

14x=80            <em>divide both sides by 14</em>

x=\dfrac{80}{14}

\boxed{x=\dfrac{40}{7}}

emilio had $150 on a gift card he used the gift card to purchase 8 dvds. adam had $175 on a gift card and used the gift card to
Artyom0805 [142]
150 - 8d = 175 - 10d
-8d + 10d = 175 - 150
2d = 25
d = 25/2
d = 12.5...so each dvd costs 12.50

150 - 8(12.5) = 150 - 100 = 50
175 - 10(12.5) = 175 - 125 = 50

so they will each have 50 bucks left on their card
