To get the answer we can use proportion
3 red ----------------- 5 yellow
x red ----------------- 20 yellow
Crossmultiply now
3*20=5x
60=5x /:5 (divide both sides by 5)
60:5=5x:5
12=x - its the answer
Answer:
y = -2
Step-by-step explanation:
y - 2 = -4
add 2 to both sides
y - 2 + 2 = -4 + 2
y = -2
Answer:

So, 2π/3 radians is equal to 120°.
Answer:
Blue line: y = -2
Red line: y = 2/3 x + 2
Perpendicular to red line: y = -3/2x + 2
Parallel to red line: y = 2/3 x + any real number
Answer:
the top middle and two at the bottom
