Answer: On khan academy, it stays the same
Step-by-step explanation:
The answer is C
Answer:
It increases
(5/x) + 5
As x decreases, 5/x increases. So the expression increases.
1. c=-2
2. 0=12 no solution
3. x=4
4. r=3/2
To find a, you need to isolate/get the variable "a" by itself in the equation:
Multiply the inverse of 1/2, which is 2, to get rid of the fraction
a - 7 = 66 Add 7 on both sides to get "a" by itself
a - 7 + 7 = 66 + 7
a = 73
