X= -2 and x= 2 are the answers
11 liters of 25% orange juice, 4 liters of 10% orange juice:
1' let x to be 25% orange juice and y be 10% orange juice
2' .25x+.10y=(15).21
3' x+y=15
4' 2.5x+y=31.5 divide all sides by 10
5' -x-y=-15 multiply all sides by -1
6' 1.5x=16.5
7' x=11
8' y=15-11=4
so 11 and 4 are the answers.
A number between 60 & 65 ??
Answer:
Laura is 15 and Luci is 15.
Step-by-step explanation:
Now...
Laura - 3x
Luci - x
In 5 years...
Laura - 3x+5
Luci - x+5
The sum of that is...
4x+10=30
-10 -10
4x=20
4/4 20/4
x=5
If...
Laura - 5 than.....
Luci - 15 because 5*3 is 15
Since that f is continuous for all x in R, and f > 0 then
for hence the asymptote is
y = 4
