Answer:
Josh is wrong.
Step-by-step explanation:
5^-x / 5^x = 5^(-x-x) = 5^-2x
= 1 / 5^2x
(you subtract the exponents when dividing )
So Josh is wrong ( he would be correct if we were multiplying)
You would write it as -4 1/2

ed 2020. I went back to check the answer so 100% right.
Hey!
--------------------------------------------------
10x = 10
To find the constant of proportionality just take the number and divide it by 1. 10x/1 = 10. The constant of proportionality can also be found by finding the slope of an expression or graph. In this case the slope is 10.
--------------------------------------------------
Thus, 10 is the constant of proportionality!
