Step-by-step explanation:
11-12/6-2 = -1/4
Answer:
$621.08
Step-by-step explanation:
The formula for the amount (A) resulting from principal P being invested at rate r continuously compounded for period t is ...
A = Pe^(rt)
Filling in the given numbers and doing the arithmetic, we get ...
A = $400e^(0.055·8) ≈ $621.08
You can say
x+y=5
x=5-y
You know the value of x, put it into the next equation.
3(5-y)-7y=19
15-3y-7y=19
15-19 = 10y
-4=10y
-4/10=y
-2/5=y
Put y value back into either equation to find value of x.
x+y=5
x-2/5=5
x=5+2/5
x=27/5
Therefore, x,y = (27/5, -2/5)
Hope I helped :)
