1. 7 2/3 + 2 7/12

1 answer:

It's just not realistic to present a list of 12 math questions and ask for the answers to all of them at once. Please post only one question at a time and please share your thoughts about how to solve that question.

I'll focus on one problem: <span>7 2/3 + 2 7/12

Here the LCD (lowest common denominator) is 12. 7 2/3 becomes 7 8/12.

Add 7 8/12 and 2 7/12:

7 8/12
+2 7/12
-----------
9 15/12 15/12 is not a proper fraction. Write it as 1 3/12, or 1 1/4.

Then your 9 15/12 becomes (9+1) 1/4, or 10 1/4.</span>

What is the expression in exponential form and value of -10x-10

mamaluj [8]

It's very important to use the symbol " ^ " here to denote exponentiation.

You probably meant "-10x^(-10), which would be "-10 times x to the minus tenth power."

If you want the value, you could do the following:

-10 1
------------------ = - ---------- = - 10^(-9).
10^10 10^9

Identify the reflection rule in the given figure.

saul85 [17]

Answer: A) Reflection along the line y = -1

===========================================================

Explanation:

Point A is at (1,5). Point A' is at (1,-7).

Apply the midpoint formula to find the center of these two points.

You should get (1,-1) as that midpoint.

Follow these steps for B(-1,3) and B'(-1,-5) to get the midpoint (-1,-1)

Those midpoints we found are located on the mirror line. We only need two such points to plot it. Drawing a line through (1,-1) and (-1,-1) graphs the equation y = -1. This is the horizontal line through -1 on the y axis.
