None of those could be a radical, you would have to have a radical symbol for it to become a radical
Answer:
y = 4/3x - 6
Step-by-step explanation:
y = mx + b
if m = 4/3 and passes through (9,6) then
6 = 4/3(9) + b
6 = 12 + b
b = -6
then y = 4/3x - 6
Answer:
y=3x+10
Step-by-step explanation:
2=-12+b
b=10
I assume you are asking one of three things, so I will answer all of them.
if you are asking what is 1/2 of 312, then multiply 312 by 1/2. 312 is really just 312/1, so

we multiply fractions by multiplying straight across

if you were asking what part of 3 1/2 is 1/2 then we have to recognize what 3 1/2 is as an improper fraction. to do this, we convert 3 into halves. how many halves of pizza are there in 3 whole pizzas? 6. so we have 6 halves and one half, which is a total of 7 halves.

now, we do the same thing as the first problem

if you were asking what is half of 3.12, then we convert 1/2 to a decimal and multiply
The sum of all angles (around the black dot) is 360°
All 5 angles (if you forget the red line) are the same; so each angle is 360°/5 = 72°
So Angle 1 is 72°
