Answer:
9^-3/9^12
Step-by-step explanation:
The answer is A because Alon could have rotated the figure and discovered that they are congruent
To find the total number of text messages sent, you will use the stem-n-leaf plot to create a data set of all the numbers of texts sent.
To read a stem-n-leaf plot you will use the number on the left as the tens place and each number to the right of it creates a new number in the data set.

Here is the list of the all the data:
0, 0, 7, 9, 10, 10, 15, 20, 23, 32
To find the total number of text messages sent, add these together.
The answer is 126 text messages.
Answer: Infinite solutions
Step 1: Turn this into y=Mx+b form
The current equation is—
-2x+5y=30
Since we want to get y alone on the left side, let’s add 2x on both sides
-2x+5y=30
+2x +2x
____________
5y=2x+30
Step 2: Again, trying to get y alone, we need to divide 5 on both sides
5y=2x+30
/5 /5 /5
________
y=2/5x+6
Step 3: Now that we know how to find y, substitute that in where y is in the equation
-2x + 5(2/5x+6) = 30
-2x + 2x + 30 = 30
30=30
Seeing that you cannot get a specific answer for y when solving, there is an infinite number of solutions
