Answers b and c are 'way off (wrong). Answer d is not negative, and thus could not be the correct answer. That leaves Answer a: the range is influenced too much by extreme values.
Answer:
C (if the sign after the digit 1,2,3,4 is not minus !!!)
Step-by-step explanation:
-10 + (-7) and -10 - 7
-10 + 7 and -10 - (-7)
-1 / -1/4 and 1(4)
-1(4) and 1 / -1/4
The hint is given by the translation with respect to the y-axis. Since the translated y-coordinate is subtracted with 4, it is translated 4 units downwards. Since the x-coordinate is added with 2, that means that<em> the original coordinate is moved 2 units to the right.</em>
For this item, we represent the very original value or price of the given item by x such that increasing the retail price by 40 percent will give us 1.4x. Also, when the retail price of the item is reduced by 25 percent, we have.
new retail price = 1.4x (1 - 0.25) = 1.05x.
This means that the new retail price is only 5% over the manufacturer price.
