Answer:
d
Step-by-step explanation:
<span>6(2x-4y)=3(2x+4)
(2x-4y)=3/6(2x+4)
2x-4y=1/2(2x+4)
2(x-2y)=1/2x2(x+2)
x-2y=1/2(x+2)
x-2y=1/2x+1
x-1/2x=1+2y
x/2-1=2y
y-y1=m(x-x1) that is slope point intercept form
now plugin some points and get according y values so u can graph</span><span />
Answer: a. (2.5, 300°) and (-2.5, 120°)
b. (4, 270°) and (-4, 90°)
<u>Step-by-step explanation:</u>
Polar coordinates are written as (r, θ) where
- r is the radius
- θ is the angle
In the first graph, the radius is 2.5 and the angle is 300° --> (2.5, 300°)
You can also list the radius as -2.5 at angle 120° --> (-2.5, 120°)
↓
(300 - 180)
In the second graph, the radius is 4 and the angle is 270° --> (4, 270°)
You can also list the radius as -4 at angle 90° --> (-4, 90°)
↓
(270 - 180)
