Answer: It is a function.
y=145+12.5x
Step 1: Swap x and y
So, x=145+12.5y
Step 2: Solve for y
So, subtracting 145 from both sides
x-145=12.5y
Divide by 12.5 from both sides
Answer:

Remember PEMDAS.
Parentheses
Exponents
Multiplication/Division
</span>Addition/Subtraction
There are no parentheses, but there is an exponent. So first you must do 3^2.
<span>20 - 2 * (3*3)
</span>20 - 2 * 9
Next is multiplication/division. Multiply -2 by 9.
20 - 2 * 9
20 - 18
Lastly, you subtract.
20 - 18
2
The answer is 2.
