To compare you should make the down part equal first
27/45 < 30/45
A=35+5t, b=100-8t, a=b when:
35+5t=100-8t subtract 35 from both sides
5t=65-8t add 8t to both sides
13t=65 divide both sides by 13
t=5 minutes
a=35+5(5)=60 gallons
So the tanks have an equal volume of 60 gallons after five minutes.
You have several possible points
. Any point that lies on the given line will have a
value that you obtain by plugging in the corresponding value of
into the equation of the line.
The line has equation
, so any point on the line will have the form
.
Among the four given points, there are only 2 different values of
to check. We have


which means the given line contains the points (4, -5) and (1, 4). So the answer is A.
Answer:
- The second option is better
Step-by-step explanation:
<u>Total for the first choice:</u>
- 8000*5.5/100 + 1500 = $1940
<u>Total for the second choice:</u>
- 8000*3/100 + 2000 = $2240
As we see the second choice is better as more salary is expected
