Answer: -74

Step-by-step explanation:

First you have to solve - 2y - 9 = 7 to find what "y" equals so we can plug that into 9y - 2

1. Solve -2y - 9 =7:

-2y = 16

y = -8

2. Plug -8 into the expression 9y - 2:

9(-8) - 2

-72 -2

-74!

Im sorry if i didnt do this correctly :/

What is the equation of the line that is parallel to the line y - 1 = 4(x + 3) and passes through the point (4, 32)?

Monica [59]

Answer:

y = 4x + 16

Step-by-step explanation:

y - 1 = 4(x + 3)

Has a slope of 4

y = 4x + c

32 = 4(4) + c

32 - 16 = c

c = 16

y = 4x + 16

What is the exact value of sin (165 degrees)

anygoal [31]

Answer:

Step-by-step explanation:

Think of a value on the unit circle that is double of 165.

330 is that so we can use the double Angle Identity

$\sin( \frac{ \alpha }{2} ) = \sqrt{ \frac{1 - \cos( \alpha ) }{2} }$

Alpha is 330

$\sin(165) = \sqrt{ \frac{1 - \cos(330) }{2} }$

$\sin(165) = \sqrt{ \frac{1 - \frac{ \sqrt{3} }{2} }{2} }$

$\sin(165) = \sqrt{ \frac{ \frac{2 - \sqrt{3} }{2} }{2} }$

$\sin(165) = \sqrt{ \frac{2 - \sqrt{3} }{4} }$

$\sin(165) = \frac{ \sqrt{2 - \sqrt{3} } }{2}$
