Answer:
-8.8517
Step-by-step explanation:
We assume you want the log of 462 to a base of 1/2. Using the change of base formula, this is ...

2x-y=5
Subtract 2x from both sides
-y=-2x+5
Multiply everything by -1
y=2x-5 would be your answer
I believe the answer is D. Let me know if you need an explanation
Answer:
4 1/2 + 1 3/5 = 6 1/10 or 61/10
Answer:
x = 2, or x = -1
Step-by-step explanation:
If 2x - 3 is inside the parenthesis (), then the value of x is 2.
If 2x - 3 is inside the absolute value sign, then the value of x will probably be -1.
<u>Solution 1</u>
(10x-15) + 4 = 9
10x -11 = 9
10x = 20 -> x = 2
<u>Solution 2</u> (Not 100% sure)
|10x -15| +4 = 9
10x + 15 +4 = 9
10x + 19 = 9
10x = -10 -> x = -1
Please correct me if I'm wrong.
