So,
In order to simplify a fraction, we have to factor both the numerator and the denominator.

Cross out ones.
X/y
x=1 when y= 5
x=2 when y =10
the constant of proportionality = 1/5
Answer:

Step-by-step explanation:
The domain of the function is the set of all possible inputs for the function. Therefore, the set of all possible inputs is
.
Answer:
No solution
Step-by-step explanation:
Actually, you have only one equation here. We will solve it for x.
Performing the indicated multiplication, we obtain:
10-2(2x+1)=4(x-2) => 10 - 4x - 2 = 4x - 8, or 10 - 2 = -8. This can never be true, so this equation has no solution.
