12^r = 13
Take the logarithm of each side of the equation:
r log(12) = log(13)
Divide each side by log(12) :
r = log(13) / log(12) = 1.03221,,, (rounded)
Answer:
C)
Step-by-step explanation:
In a parallelogram, if one angle is 90 (right angle), then it is a rectangle
Answer:
I can't see because it is sideways
2x + y = 8
x + 3y = -6
Note: This is the process of elimination
First: Multiply one side by -3 to get rid of your y's.
It should look like:
-3 ( 2x + y) = 8 (-3)
Then it should look like:
-6x - 3y = -24
x + 3y = -6
Go ahead: Get rid of the y's
Your equation should then look like:
-6x = -24
x = -6
Next: You would add x to -6x and subtract -6 from -24.
It should look like:
-5x = -30
Finally: You would get your x alone and divide both sides of your equal sign by -5.
Remember: Negative and a negative makes a positive.
Your answer should be:
x = 6
