Answer:
<h2>PART A: x = 15 and y = -8</h2><h2>PART B: x = -5 and y = 3</h2>Step-by-step explanation:
PART A:
The first equation is
The second equation is
Putting the value of y from (a) in the above equation, we get
From (a) we get y = 7 - x = 7 - 15 = -8
PART B:
Here the system of equations are
From (a) we get,
Putting the above value of x in (b) we get,
Hence,
Answer:
The rate of interest for compounded daily is 2.1 6
Step-by-step explanation:
Given as :
The principal investment = $ 98,000
The Time period for investment = 7 years
Let The rate of interest compounded daily = R %
The Amount at the end up = $ 114,000
<u>From compounded method</u>
Amount = Principal ×
Or, $ 114,000 = $ 98,000 ×
Or, =
or, 1.16326 =
or, = 1 +
1.00005919 - 1 =
or, 0.00005919 =
∴ R = 0.00005919 × 365000 = 2.16
Hence the rate of interest for compounded daily is 2.1 6 Answer
