Answer:
x = -0.5
Step-by-step explanation:
Here we have the sentence:
"3 to the power 2x+3 is subtracted by 9 which is equal to 2 times 9 to the power x+1 and is subtracted by 6"
The first part:
"3 to the power 2x+3 is subtracted by 9..."
This can be written as:
"... is equal to 2 times 9 to the power x+1 and is subtracted by 6"
Let's solve this for x.
First, we can add 9 in both sides:
We also know the relations:
and
We can write the left part as:
And the right side as:
Then the equation becomes:
Now let's move both terms with 9^x to the left side:
Now remember that:
Ln(a^b) = b*Ln(a)
Then if we apply the Ln( ) function to both sides, we get:
Answer:
-3
Step-by-step explanation:
First, you look at which way it is going. From left to right, the line is going down, so the slope is negative. Change in y is 3 and change in x is 1. From any two points on the line, the y value changes by 3 every time the x value changes by 1.
Answer:
Its 100 percent B
Step-by-step explanation:
first u multiply 3 which will give u 3V on the left side.
then you divide pie times radius squared which will give you 3V divided by pi radius squared equal to H which is the height
That is the centroid.
The point where the lines from each vertex of the triangle to the midpoints of the opposite sides intersect.
Answer:
$21
Step-by-step explanation:
$20 for the 500 minutes
We still have to pay for 10 minutes.
10 cents per minute.
10centsx10 minutes.
100 cents, also known as 1 dollar.
$20 plus $1 means the answer is $21.
Hope this helps!
