First, you do 1/4 • 9 to find the total amount that is in the bag, which is 2 1/4 cups. Then, you do 2 1/4 - 5/8 to find out how much is left in the bag. There is 1 5/8 cups of trail mix left in the bag.
Make one of the variables drop out.
I'd go for the y since it's easiest in this problem.
Time the top equation by -1.
This changes the system to:
Add the equations.
The equation would be:
Or simply:
Solve for x by dividing.
Then, plug x into one of the original equations to find y.
I'm going to use the first one since the numbers are smaller, but you CAN use either.
Put these into an ordered pair.
(0,1)
That is your answer.
Hope this helped!

Answer:
-2√3+2√15
Step-by-step explanation:
Answer:
275
Step-by-step explanation:
t = total sold
c = cheeseburgers h = hamburgers
c + h = t total is equal to cheeseburgers + hamburgers
we know that
c + h = 481
and that c = h - 69
so we can rewrite the first equation as
(h-69) + h = 481
2h = 481 + 69
2h = 550 h=550/2=275
so there 275 hamburgers were sold
Answer: Opens up, has a minimum
Step-by-step explanation:
If the x^2 term is positive the parabola opens up, if it is negative it opens down. Minimum always goes with up, maximum with down
