Answer: Third option
Step-by-step explanation:
You have the function:

Then, if the value of x increases by 1, you obtain:
-Rewrite the function:
-Substitute values for x into the function and observe what happen to y. Then:
x=1
x=2
x=3
The value of y is doubled.
Answer:
x = 3
Step-by-step explanation:
The fractions need to have common denominators. So, we would make the common denominator (x + 3)(x - 3), or, x^2 - 9
Multiply the numerator by the same number or variable as the denominator and then combine.
Once their is x and a number left you would solve for x.
Answer:
2(2/5x+2)= 2*2/5x + 2*2= 4/5x+4
