if the class charges $15 per ticket write an equation that could be used to determine the number of tickets the class would need
OverLord2011 [107]

t = number of tickets

15t ≥ 1500

so....

step 1. 15t ≥ 1500 --> divide both sides by 15 --> 15t/15 ≥ 1500/15

step 2. t ≥ 100


So 100 at the least, ticket should be sold to reach atleast $1500.


I hope this helps. :)

The graph below is a portion of a complete graph. Which graph below is the complete graph assuming it is an even function?
Ierofanga [76]

Answer:

Option b

Step-by-step explanation:

A function is even if and only if f(-x) = f(x).

This means that there is the same value of y for x_0 and for -x_0

Where x_0 is any point belonging to the function .

Therefore you must select a graph whose ordered pairs are of the form (x_0, y_0) and (-x_0, y_0)

Therefore the correct answer is option b. Assume that each box in the graph equals 1 unit. Then, for x = 2 y = -3 and for x = -2 y = -3. Then it is shown that the function is even.

-5/6+ -5/6 please help me
ehidna [41]
(-5/6)+(-5/6) have the same denominator (number at bottom of fraction), so all you have to do is add the numerator(top number). So -5 +-5 =-10 . Now you have -10/6, which simplifies to -5/3. 
Hope this helps :)
