Answer:
79
Step-by-step explanation:
Let the original number be x.
x/2 = 39.5
x = 39.5 × 2
x = 79
The solution to the system of equation are (0, -2) and (1, 0)
<h3>Solution to system of equations</h3>
System of equations are equations that has unknown and more than 1 equations.
Given the system of equations
y = x^2 + x – 2
y = 2x – 2
Equate both expressions
x^2 + x -2 = 2x - 2
x^2 - x = 0
x(x-1) = 0
x = 0 and x - 1 = 0
x = 0 and 1
If x = 0
y = 0 - 2 = -2
If x = 1
y = 2 - 2 = 0
Hence the solution to the system of equation are (0, -2) and (1, 0)

This is quite simple, you can see that the x-axis stays the same so then you know that it is a vertical line. You can tell because any point on this line will be (2,x). So to graph it, you draw a vertical line where x=2
<span>Answer:
The credit card issuer will show APR which is 22.08% and not effective rate of interest.
This is because Effective rate, when calculated with the formula given below will come as 24.67% which is 2.59% more and hence will make customers feel that they are paying more.
r = [ { (1+ i / n) ^ (n) } - 1] * 100
Where i = APR/100
n = number of compounding periods which is 365 in this case as compounding is done daily.
[ { (1+ 0.2208 / 365) ^ (365) }- 1] * 100</span>
