Domain is all Real Numbers and Range is from 0, but not including 0, to infinity. So it would be the first one
Answer:
a = 540°
b= 180°
Step-by-step explanation:
a= pentagon has 5 sides which means 180 × 5= 540
b= 540÷5=180
18/60 which is equal to 3/10
So you just need to put it into proportions which is blue to total. The total is 60 and there is 18 blue. Then you only need to simplify.
Y=-68
Hope this helps, have a great day!
Answer: M = 
Step-by-step explanation:
M (x + y) + 4y = x + 2y (Multiply 
in both sides)
M (x + y) = x + 2y - 4y
M (x + y) = x - 2y (Divide (x+y) from both sides)
M =
