What is the solution to the system of equations? x+y=5 x-2y=2 (_,_)

You can use the substitution method. Using the first equation in terms of y,
y = 5 - x
Substitute this to the second equation to get the value of x.
x - 2(5 - x) = 2
x - 10 + 2x = 2
3x = 2 + 10
3x = 12
x = 4

For y, just substitute the value of x that we have used in the first equation.
y = 5 - 4 = 1

Therefore, in coordinate form, that is (4,1)

$4750 invested at 10% p.a compounded semiannually for 10 years, calculate the interest
alexgriva [62]
<h3>Answer:  $7,853.16</h3>

Work Shown:

A = P*(1+r/n)^(n*t)

A = 4750*(1+0.10/2)^(2*10)

A = 12,603.164099436

A = 12,603.16

That represents the account balance after 10 years. To find the interest only, subtract off the deposit amount.

interest = A-P = 12,603.16 - 4,750 = 7,853.16
