Answer:12 and 1/4
Step-by-step explanation:
Multiply 7 times 1 and then multiply 7 times 3 and divide by four
X + y = 12
x - y = 4
(12 - 4) : 2 = 4
4 + 4 = 8
x = 8
y = 4
-----------------------
8 + 4 = 12
8 - 4 = 4

Answer:
$794.30
Step-by-step explanation:
The account balance for principal P invested at rate r compounded daily for t years is ...
A = P(1 +r/365)^(365t)
We have P=$9538, r=0.08, t=1, and we want the value of P-A, the interest earned.
P-A = P(1 +0.08/365)^365 -1) = $9538(1.08327757 -1) ≈ $794.30
The interest earned in one year is $794.30.
1. 2^2=4
Sqrt(2) ≈1.4
4+1.4=5.4
2. -2^2 = -4
Sqrt(-2) = -1.4 i -> 1
3. 3x + 2 = 14
3x=12
X= 4
