Answer:

Step-by-step explanation:
We were originally on -1.
But we jumped to -4.
-4 is 3 spaces to the left of -1.
In other words, we subtract 3 into -1.
Another way of saying this is that we added -3 to -1.
Therefore, our equation is:

8-(2/x)
"Minus" means subtraction, and "quotient" means division.
Answer:
y = 18 when x = 3
Step-by-step explanation:
y is directly proportional to x^2, meaning:

where a is the proportion between them. We're given the values for both x and y, so plug those in and solve for a:

Now you can use a to solve for y when x is 3:

-3/12 - 20/12 is equivalent to -1/4 - 5/3
