Answer:
A computer costs $225 and a printer $150.
Step-by-step explanation:
Let c be the cost of a computer and p the cost of a printer, then:
3c + p = 825
4c + 2p = 1200
Multiply the first equation by -2:
-6c - 2p = -1650
Add this to the second equation:
-2c = -450
c = 225.
Now substitute c = 225 in the first equation:
3*225 + p = 825
p = 825 - 675 = 150.
Answer:
The graph of the function 
is attached as image below.
Analysis:
We have two intersection points in the graph
The function intersects the y-axis at points (0,4)
The function intersects the x-axis at points (-16,0)
f(x) is positive for x>-`16
f(x) is negative for x<-`16
42 drank iced tea
60 drank either water or lemonade
So the ratio would be 42:60 or 7/10 as a fraction.
So D is the correct answer
Answer:
6840
Step-by-step explanation:
Well we know there's 24 hours in a day so dividing that by 1440 we get 60. Now we know that it consumes 60 watts ever hour. so now we just have to figure out how many hours there are and times that by 60. So there are 96 hours in 4 days plus 28=114. So times that by 60 ( watts) 114×60=6840
So that's your awnser.
