Slimination
multiply first equaiton by 2
2x+6y=10
add to second equiaotn
2x-2x+6y-6y=10-10
0=0
this is true so therfor they are the same equaiton
so solve
x+3y=5
3y=-x+5
y=-1/3x+5/3
subsituter values for x and get valuse for y
if x=2 then y=1
False. Although, I'm not 100% sure.
In a Fibonacci Sequence, the following applies:
1,1,2,3,5,8 etc.
Where the following term is a sum of the 2 previous terms.
Relate this to the terms in your question:
1, 1, 2, 5, 8
Goes to:
Y-x, x, y, x+y, x + 2y
Since to get y you add the 2 previous terms
y-x + x = y
y + x = y + x
x + y + y = x + 2y
Hope this helps you :)
You used multiplication of 2 terms which is where you went wrong.
Answer:
your answer is 1
Step-by-step explanation:
1+1 divided by 1-1=1
X >= (at least symbol) $9 since she needs AT LEAST 20$ and she already has 12$ so 12+9>20
