Sure you do  !
I'll tell you what it is, and why, and you'll slap your forehead
and call yourself names.

The 'standard'  form of an equation that shows the slope and intercept is

                                      y = (slope) x + (intercept)

<em><u>What if the slope is zero</u> ?</em> 

Then the equation is                y = (0) x + intercept
                                             or
                                                     y = intercept.

Does that look anything like    y = -3  ?

(4/9)^-1=<br><br><br>A. -4/9<br><br>B. 9/4<br><br>C. -9/4
Romashka-Z-Leto [24]

Answer: 9/4

Step-by-step explanation: Think of (\frac{4}{9})^{-1}as \frac{4^{-1} }{9^{-1}}.

Now, we can change 4⁻¹ to 4¹ by moving it to the denominator and

we can change 9⁻¹ to 9¹ by moving it to the numerator.

So we have 9¹/4¹ which simplifies to 9/4.

Find the area of a regular decagon with perimeter 100 units. Show all work.
Slav-nsk [51]
A regular polygon has ten (10) equal sides ( since it is regular).
We are given with the perimeter value which is 100 units and the perimeter formula is P = 10a
Solving for a (the side measurement), we have:
100 = 10a
a= 100/10
a =10

We can now proceed in solving the area and the formula is shown below:
Area = 5/2 a√ (5+2√5)
Area = 5/2 * 10√(5+2√5)
Area = 76.94 square units

The answer is 96.94 square units.
