In a function, each domain element can have at most one range element. So we'll have to remove one of the links from 3. Either one can be removed, since it is OK for two domain elements to map to the same range element (as is the case for 3->b and 4->b).
This is all very theoretical, but here is a real life example.
Take f(x) = x²
You probably know that both f(2) and f(-2) is 4.
There 2 and -2 are in the domain, 4 is in the range.
Answer:
A. –x – 6y = 42
Step-by-step explanation:
Multiply everything by 6:
6y = x + 42
The answer you are looking for is -6y+x=-42
We start by multiplying everything by 6
·6y=X+42
We then need to move X to the other side of the equation so we subtract X rom both sides.
·6Y-X=42
In order to solve the question X must be positive so we multiply everything by a quanitity of -1
·-6y+x=-42
Now this is in stardard form, so in conclusion your answer is -6y +x = -42

The standard form of a straight line equation is: Ax%2BBy%2BC=0
.
In your example, we would write:

Answer:
0.5 t
Step-by-step explanation:
Since we know that 2,000lbs=1 t
1,000lbs is half a ton, which makes it 0.5 tons
