Answer:
Step-by-step explanation:
We start by adding 
to both sides, giving 
, which after simplifying gives 
.
We then add 
to both sides, giving 
, which after simplifying gives 
.
We can then divide both sides by 
, giving 
, which after simplifying gives 
, or . So, x is 5.
The domain would negative infinity to positive infinity . Domain would be the smallest through the largest possibly value of X. If you also need the range it’s ( -4,infinity]
To find how many miles per hour you need to divide 50 by 5 to get the number of miles per hour and do the same thing to the 2nd step and to find the difference you need to subtract the numbers. Hope it helps!!!
