Answer:
A
Step-by-step explanation:
To know the distance between the two on a number line, we subtract both numbers from each other
Since the absolute value will give the same result irrespective of the number we used first, we can see that it is the first option that would give the needed results
This means that option A is our answer
Answer:
Step-by-step explanation:
<u><em>(1).</em></u> (x - <em>h</em>)² + (y - <em>k</em>)² = <em>r</em>²
where <em>(h, k)</em> are coordinates of a center of the circle with radius <em>r</em>
<u><em>(2).</em></u> ( a ± b )² = a² ± 2ab + b²
~~~~~~~~~~~~~~
( 1 , - 2 ) ; r = 3
( x - 1 )² + ( y + 2 )² = 3²
x² - 2x + 1 + y² + 4y + 4 = 9
x² + y² - 2x + 4y - 4 = 0
a = - 2
b = 4
c = - 4
Answer:
a) Somebody was kung-fu fighting for less than 10 hours.
b) All rivers have less than two tributaries.
Step-by-step explanation:
To write minimal negation statements, one must abide by the following rules:
1. If all Xs are Y ⇒ There is one X that is not Y
2. If one X has Y⇒ All Xs do not have Y
a) "Everybody was kung-fu fighting for at least 10 hours"
Following the first rule:
Somebody was kung-fu fighting for less than 10 hours.
b) "There is a river with at least two tributaries"
Following the second rule:
All rivers have less than two tributaries.
So, to find the day rate, we divide 90 by 6 = 15
So then we find 15n = 300 for the rate.
n = 20
It will take Stephen 20 days to read a 300-page book
Im pretty sure it would be 26 because you can buy 25 hamburgers at the price of 5 for $9 and then buy one for $3.
