we have the function

For x=2
substitute

therefore
<h2>the answer is 4.20 million dollars</h2>
X + y = 23000
x.08 + y.09 = 2040
x = 23000 - y
(23000 - y) .08 + y.09 = 2040
1840 - .08y + .09y = 2040
Simplify
.01y = 200
Simplify
Y = 20000
X + 20000 = 23000
X = 3000
CHECK: .08x + .09(20000) = 2040
.08x + 1800 = 2040
Simply .08x = 240
X = 3000
Answer:
Step-by-step explanation:
10^2+3^2=109 and sqrt 109 getting 10.4
Answer:
$3.60
Step-by-step explanation:
