The selling price of an apartment dropped from 250,000 to 225,000. By What percent did the price drop?
1 answer:
Answer:
10%
Step-by-step explanation:
The percentage decrease in price = x 100%
Original amount = 250,000
New amount = 225,000
Decrease in amount = 250,000 - 225,000
= 25,000
So that;
Percentage decrease in price = x 100%
= 0.1 x 100%
Percentage decrease in price = 10%
The price of the apartment dropped by 10% of its original price.

Subtract 3 from both sides,
Let x = X and y - 3 = Y
Then,
So, we have shifted the origin to a point (0, 3).
This is an odd function and the graph of an odd function is symmetrical about the origin.
That is, symmetrical about X = 0, Y = 0
Symmetrical about x = 0,, y - 3 = 0
Symmetrical about x = 0, y = 3.
Hence, the graph is symmetrical about the point (0, 3).
