Answer:
Sylvia needs 12 l of orange juice and 9 l of pineapple juice.
Step-by-step explanation:
triple means multiplying by 3
so multiply 4 l of orange juice by 3 and 3 l of pineapple juice by 3
X-y=3=>x=3+y
X+2y=-6
=========
3+y+2y=-6
3+3y=-6
3y=-6-3
3y=-9
y=-3
X+2y=-6
X+2(-3)=-6
X-6=-6
X=0
Answer:
yes

<u>Exponential Equations</u>
Solve:

Separate each exponential:

Operating:

Multiplying by 5:

Rearranging:

Recall that:


Calling


Factoring:

There are two possible solutions:
y=25
y=-50
Since

y cannot be negative, thus:

The solution is:
x = 2
