Answer:

(-1/2,2)

Step-by-step explanation:

2(4x+y=0)=8x+2y=0

8x+2y=0

-(8x-y=6)

3y=6

Divide both sides y=2

4x+2=0

4x=-2

divide both sides x=-1/2

M&lt;1 and m&lt;2 are vertical angles if m&lt;1 = 106° and M&lt;2 equals 20x - 14 find M&lt;2
just olya [345]

Answer:

Answer:

m∠2= 86

Step-by-step explanation:

since they are vertical angles, that means they are both equal to eachother.

so lets set them equal!

17x+1=20x-14

17x+15=20x

15=3x

x=5

now input x into m∠2

m∠2 = 20(5) – 14 = 86

(Q2) Determine the eccentricity, the type of conic, and the directrix for r = 9/1+cos theta
g100num [7]

Answer:

The answer is (d) ⇒ eccentricity = 6 , hyperbola , directrix  x = 3/2

Step-by-step explanation:

∵ r = ek/(1 ± ecosФ)

∵ r = 9/(1 + 6cosФ)

∴ e = 6 ⇒ eccentricity = 6

∵ e > 1

∴ The conic is hyperbola

∵ ek = 9

∴ k = 9/6 = 3/2

∴ The directrix  x = 3/2

Graph the line with slope 3/2<br> and y-intercept - 7.
Ronch [10]

Answer:

14=3x-2y

y = m x+ c \\ y =  \frac{3}{2} x - 7 \\ y =  \frac{3x - 14}{2}  \\ 2y = 3x - 14 \\ 14 = 3x - 2y \\ therefore \\ 14 = 3x - 2y \: is \: the \: required  \: eqution \: of \: the \: line

it can be wrong also
