4+4v = 3v +4
------- = -----------
-3 2
use cross products
(4+4v) *2 = -3*(3v+4)
distribute
8+8v = -9v-12
add 9v to each side
8+17v = -12
subtract 8 from each side
17v = -20
divide by 17
v = -20/17
Answer:
see the attachment
7 hours
Step-by-step explanation:
The cost for River Y is a constant (not dependent upon hours), so is c = 41.
The cost for River Z is the sum of the deposit and the hourly cost, so is ...
c = 13+4n
These equations and their graphs are shown in the attachment. The graphs cross where n=7, indicating you have to rent a canoe for 7 hours for the cost to be the same on both rivers.
0.59 and 2/3
0.59
0.66
0.59 < 2/3
2/3 is greater than 0.59.
Answer :
Let b=height of building. By similar triangles we can say:
b/44.75=3.1/1.29
b=44.75*3.1/1.29
b≈107.54
b≈108 meters (to the nearest whole meter)
What is the domain and the range of the relation represented by the ordered pairs? {(6,6),(−1,3),(3,6),(0,4)}{(6,6),(−1,3),(3,6)
Inessa [10]
Hello,
Let's review: The domain is all the possible x values of a relation/function. To get the domain, we look at the x values in the ordered pairs.
The domains are: {-1, 0, 3, 6} - as you can see these are the x values of each pair.
Let's review: The range is all the possible y values in a relation/function. To find the rang, we look at the y values of the pairs.
The ranges are: {3, 4, 6} - notice how there are two "6" in those pairs, and when writing the range, you don't need to repeat the number if it's already written.
I hope this helps! =)
