Determine the equation of a line through the point (3,-4) that is perpendicular to the line y=3x+7
Lana71 [14]

Answer:

y = - \frac{1}{3} x - 3

Step-by-step explanation:

The equation of a line in slope- intercept fprm is

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

y = 3x + 7 is in slope- intercept form

with slope m = 3

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

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

y = - \frac{1}{3} x + c ← is the partial equation of the perpendicular line

To find c substitute (3, - 4) into the partial equation

- 4 = - 1 + c ⇒ c = - 4 + 1 = - 3

y = - \frac{1}{3} x - 3 ← equation of perpendicular line

Plssss help <br> I need AC
Zolol [24]

Answer:

AC = 18

Step-by-step explanation:

Using the cosine ratio in the right triangle and the exact value

cos30° = \frac{\sqrt{3} }{2} , then

cos30° = \frac{adjacent}{hypotenuse} = \frac{AC}{AB} = \frac{AC}{12\sqrt{3} } = \frac{\sqrt{3} }{2} ( cross- multiply )

2 AC = 12\sqrt{3} × \sqrt{3} = 12 × 3 = 36 ( divide both sides by 2 )

AC = 18
