Answer:
Step-by-step explanation:
3(2x + 7) - 2 (x + 5)
need to distibute
5x+10-2x+3
combine like terms
3x+13
divide
x=4.3
Write out the governing equation:
y = kx.
Take any point from the given table. You haven't shared the table, so I will invent a point: (2, 9).
Then find k: k = 9/2 Then the equation becomes y = (9/2)x.
Now let x = 7 and find y: y = (9/2)(7) = 63/2
Answer: y = 63/2
Answer:
The answers are 23, 9,200 and 26, 10,400
Step-by-step explanation:
Answer:
360
Step-by-step explanation:
The exterior angles always add up to 360 in a polygon because it's the sum of all the vertexes which would make a circle.
First, you'll use the "Log power rule," which says that
. In this case, you're going from the form on the right (with p in front of the log) to the form on the left (with p in the exponent position). So, the expression becomes:
Then, you'll use the "Log product rule," which says that
. Again, you're going from the form on the right to the form on the left (basically, from the sum of the logs, to a log of the products). So you get:
There's your expression simplified into a simple logarithm.
