My guess is Answer D: 120
Answer:
y = 0.9x
Step-by-step explanation:
A movie theater sends out a coupon for 10% off the price of a ticket, so the price of the ticket with the coupon is 100% - 10% = 90% of the original price.
Let
x = original price
y = price of the ticket with the coupon
Then
x - 100%
y - 90%
Write a proportion:
Cross multiply:
Since the original price and final price are always greater than 0, then the graph of this equation is in the first quadrant (see attached diagram)
Answer:
Your answer is: C) 3
Step-by-step explanation:
The formula used to find side A in this problem is called the Pythagorean Theorum. The formula is as follows: a = the square root of c squared minus b squared. Or, you can say that the hypotenuse is equal to: c = the square root of a squared and b squared added together. This might sound confusing in the start, but here's all you have to do. c^2 = 25. 4^2 = 16. 25 - 16 = 9. The square root of 9 = 3. C) 3 is your answer.
