answer
8/25
Step-by-step explanation:
so you would keep the first fraction (2/15) then you would change the symbol then you would flip the other fraction (5/12). then you would multiply 2*12=24 and 15*5=75. then you would simplifie it. it would be 8/25.
Substitute in the values and solve.
1) B
For A:
3 = 4(1)
<u>This is NOT true.</u>
For B:
-4 = 4(-1)
<u>This IS true.</u>
For C:
-1 = 4(-4)
<u>This is NOT true.</u>
For D:
-4 = 4(1)
<u>This is NOT true.</u>
2) None. Possible solutions: (0,2) (1,-5)
For A:
2 = -7(1) + 2
2 = -7 + 2
<u>This is NOT true.</u>
For B:
-52 = -7(8) + 2
-52 = -56 + 2
<u>This is NOT true.</u>
For C:
-35 = -7(5) + 2
-35 = -35 + 2
<u>This is NOT true.</u>
For D:
-7 = -7(1) + 2
-7 = -7 + 2
<u>This is NOT true.</u>
Equal expressions can be taken equal to an another variable. The system of equations representing the equation is 
<h3>What is logarithm and some of its useful properties?</h3>
When you raise a number with an exponent, there comes a result.
Lets say you get
Then, you can write 'b' in terms of 'a' and 'c' using logarithm as follows
Some properties of logarithm are:
Log with base e = 2.71828... is written as 
simply.
Log with base 10 is written as 
simply.
The given equation is:
Adding 
on both the sides, we get:
The, we get two equations as:
This is the needed system of equations.
