Given:
The expression is 3.8 - 2.923.
To find:
The subtraction.
Solution:
We have,

It can be written as

Now,
3 . 8 0 0
-2 . 9 2 3
-----------------
0 . 8 8 7
-----------------
So, 
Therefore, the value of
is 0.887.
Make an x and y table, and pick any values to plug in for x in the equation.
I will use the numbers from -2 to 2
Now plug in the values you picked for x into the equation to find its y-value
x = -2
y = 3x - 1 Plug in -2 for x
y = 3(-2) - 1
y = -6 - 1
y = -7
x = -1
y = 3x - 1
y = 3(-1) - 1
y = -3 - 1
y = -4
Do the same for the rest of the numbers, and graph each point and draw a line connecting them.
Everything should be capitalized. If "dear" is the beginning of a sentence, it should be capitalized. "aunt" and "mary" are a name so they should be capitalized too.
