Hey there :)
To find the slope with <em>two points</em> we will need to use the equation ![\frac{y^2-y^1}{x^2-x^1}](https://tex.z-dn.net/?f=%5Cfrac%7By%5E2-y%5E1%7D%7Bx%5E2-x%5E1%7D)
![y^2](https://tex.z-dn.net/?f=y%5E2)
( 3 , -20 ) ( 5 , 8 )
Here is what the equation should look like when replaced with the numbers (<em>it will be a fraction</em>) :
![\frac{8 - (-20)}{5 - 3}](https://tex.z-dn.net/?f=%5Cfrac%7B8%20-%20%28-20%29%7D%7B5%20-%203%7D)
We know that <em>two negatives</em> cancel out and make a positive, so the numerator would actually be 8 + 20.
Solve the fraction and we get ![\frac{28}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B28%7D%7B2%7D)
28 <em>divided</em> by 2 is 14. The slope is 14.

Step-by-step explanation:
log(log 10¹⁰⁰)
= log 100
= log 10²
= 2
<em>Note :</em>
log 10ⁿ = n
<u>Answer:</u>
x = 6.00001
<u>Step-by-step explanation:</u>
We are given the following log problem to solve for x:
log(x) + log(3) = log(18)
log(x) + 0.477121 = 1.255273
Adding -0.477121 to both the sides to get:
log(x) + 0.477121 + (−0.477121) = 1.255273 + (−0.477121)
log(x) + 0 = 0.778152
Dividing both the sides by 1 to get:
log(x) + 0/1 = 0.778152/1
log(x) = 0.778152
Solving the logarithm to get:
log(x) = 0.778152
10log(x) = 100.778152
x = 6.00001
Answer:
2r-3(r+7)-8r=10(r-1)
2r-3r-21-8r=10r-10
-9r-10r=-10+21
-19r=11
-19/11=r
