Answer:
C
Step-by-step explanation:
15% off of $27 is $22.95
40% off of $22.95 is $13.77
Parallel, therefore gradient is the same = 2
y-y1=m(x-x1)
y+2=2(x-3)
y+2=2x-6
y=2x-8
Option A
Answer:
The average rate of change is -0.034 which means that the decrease is -0.034 in the cost of per print per year
Step-by-step explanation:
Given that
Price of print in 2002 = p1 =$0.50
Price of print in 2013 = p2 =$0.13
y1 = 2002
y2 = 2013
The rate of change is given by the formula:

Here decrease is the change in price and run is the difference in years.
Mathematically, it can be written as:

Putting the values

Hence,
The average rate of change is -0.034 which means that the decrease is -0.034 in the cost of per print per year
Answer:
2/5 or 40%
Step-by-step explanation:
total students=30
female students=18
That must mean, assuming the rest of the class is binary male=12
12/30=2/5 or 40% if you multiply by 20, then multiply by 100%
(2/5)*20=.40*100%=40%
