Half one is 1/2;
half three is 3/2;
Thus, if f(x) represents annual growth, f(x)/2 shows it every half-year, like this:
Written in plain text: f(x)=15/2*2^x
Answer:
(x + 15) / 2
Step-by-step explanation:
Distance = rate × time
d = (x² – 225) / (2x − 30)
d = (x – 15) (x + 15) / (2 (x – 15))
d = (x + 15) / 2
Sin0 actually will equal cos(pi)/2. this is because sin0 is equal to 0, but cos0 is equal to 1. therefore, that cannot be correct.
Answer:
21 child tickets.
Step-by-step explanation:
Let x represent number of adult tickets and y represent number of child tickets.
We have been given that on Thursday, three times as many adult tickets as child tickets were sold. We can represent this information in an equation as:
We have been given that at a the movie theater, child admission is $6.10 and adult admission is $9.20.The all tickets were sold for a total of $707.70. We can represent this information in an equation as:
Upon substituting equation (1) in equation (2), we will get:
Therefore, 21 child tickets were sold on Thursday.
