(ab)/c=a(b/c)
and
b/b=1 when b=b


1.
8+9t+4=
8+4+9t=
12+9t=
9t+12

2. (56ab)/b=56a(b/b)=56a(1)=56a

3. divising negatives yeilds positive
-46/-2=46/2=23

Find x (in degrees) in the following quadrilateral.
Ber [7]

Answer:

x = 110°

Step-by-step explanation:

The sum of the interior angles in a quadrilateral is 360°. This means:

x + x + x - 30 + 1/2x + 5 = 360° - we can simplify this

3 1/2x - 25 = 360° - now add 25 to both sides

3 1/2x = 385 - finally divide both sides by 3 1/2

x = 385 ÷ 3.5 = 110

x = 110°

Hope this helps!

The graph of y=1/x is shown below. Draw the graph of its inverse.
lord [1]
Y=1/x  solve for x

x=1/y  now reverse lables...

y=1/x  

Yes that is the same equation you started with.  What that means is the the inverse function in this case produces the same exact graph :)

An=11+(n-1)(4)<br> how do you write this in the recursive formula?
LUCKY_DIMON [66]
The answer is
\begin{cases}A_1 = 11 \\ A_{n} = A_{n-1}+4\end{cases}
----------------------------------------------------------------------------------------------
Explanation:
The first term is A_1 = 11. The next part of the rule, which says A_{n} = A_{n-1}+4 is the recursive part. To get the nth term, we add on 4 to the previous (n-1) term. For example, to get the fifth term, you add on 4 to the fourth term. Relying solely on this recursive definition means we need to find all of the previous terms (from 1 to n-1) in order to find a given nth term.
