Step-by-step explanation:

\sin(30)  =  \frac{y}{12}  \\ y = 6 \\   \cos(30)  =  \frac{x}{12 }  \\ x = \sqrt{108}  =  6 \sqrt{3}

Write an equation for the line parallel to y= -2x+1 that contains (-2,5)
grin007 [14]

Answer:

y = - 2x + 1

Step-by-step explanation:

Parallels line have the same slope, when an equation is in the form y= mx + b, m is the slope. In this problem slope = - 2

Now with the slope what is missing is the y-intercept, the problem says that the line contains the point (-2, 5), replacing that point in the equation you can solve it to find the y-intercept

y = mx + b

5 = (-2)(-2) + b

5 = 4 + b

1 + b

y = - 2x +1

Select the equation of the line that passes through the point (5, 7) and is perpendicular to the line x = 4.
Vedmedyk [2.9K]
If the line is perpendicular to x = 4, then that means the answer should be y = some number

and since we have the equation going through point (5,7), we look at the y-value since our equation is y=some number and replace the y-value into that equation.

So the correct answer is C. y = 7

Hope that helps :)
