Answer:
7. C
8. D
Step-by-step explanation:
7. The interest rate is 8% or .08. You find that by solving I=Prt (interest=original amount*rate*time in years)
8. The discounted price would be $48 (80*(1-.40)) Then you multiply that 48 by .08 and add that amount to the $48.
Answer:
The equation of the new line is 
Step-by-step explanation:
Reflecting a function over the x-axis:
Suppose we have a function y = f(x)
Suppose y' is the function y, reflected over the x-axis. Their relation is:
y' = -y
In this question:
Line with equation 
Reflection over the x-axis:
We have that:
The equation of the new line is
