Answer:
Step-by-step explanation:
First off, let's change everything to a common denominator. This will allow us to add the fractions!
To find a common denominator, we find a number that both 4, 28, and 1 can go into. 28 is the best choice, as 4 goes into it 7 times, 28 goes into it once, and 1 goes into it 28 times.
Let's change the first fraction into a number with a denominator of 28!
= 1. Multiplying a number by one doesn't change its value.
The second fraction, 
, already has a denominator of 28, so we don't have to do anything with it.
Now to the third number, -1:
Now, let's add them all up!
One last step, to simplify:
<h2>Your answer is 1/14!</h2>
Answer:
x = 25
Step-by-step explanation:
Those 2 angles together form a straight line which is equal to 180°. So you can set up an equation:
3x + 18 = 93
-18 -18
3x = 75
Divide both sides by 3
x = 25
Answer: Logarithmic
Explanation:
This curve is a reflection of the exponential curve over the line y = x, to show that it is the inverse of exponentials. We use logs to help isolate the exponent among other useful properties.
Answer:
Step-by-step explanation:
First, find the <em>rate of change</em> of the line:

Now plug all the information into the Slope-Intercept Formula. It does not matter which ordered pair is chosen:
![\displaystyle 3 = -3[2] + b \hookrightarrow 3 = -6 + b; 9 = b \\ \\ \boxed{\boxed{y = -3x + 9}} \\ \\ OR \\ \\ 6 = -3[1] + b \hookrightarrow 6 = -3 + b; 9 = b \\ \\ \boxed{\boxed{y = -3x + 9}}](https://tex.z-dn.net/?f=%5Cdisplaystyle%203%20%3D%20-3%5B2%5D%20%2B%20b%20%5Chookrightarrow%203%20%3D%20-6%20%2B%20b%3B%209%20%3D%20b%20%5C%5C%20%5C%5C%20%5Cboxed%7B%5Cboxed%7By%20%3D%20-3x%20%2B%209%7D%7D%20%5C%5C%20%5C%5C%20OR%20%5C%5C%20%5C%5C%206%20%3D%20-3%5B1%5D%20%2B%20b%20%5Chookrightarrow%206%20%3D%20-3%20%2B%20b%3B%209%20%3D%20b%20%5C%5C%20%5C%5C%20%5Cboxed%7B%5Cboxed%7By%20%3D%20-3x%20%2B%209%7D%7D)
