No more than 33 texts a month
you know the total amount spent, you know the total of the bill without texts
45=39.99+.15t
5 girls, 5 boys...total of 10 students
P(1st pick is a girl) = 5/10 which reduces to 1/2
P(2nd pick is a boy) = 5/9
P (both) = 1/2 * 5/9 = 5/18 <=
Step-by-step explanation:
The given function is :

(a) To find f(9), put x = 9 in the above expression.

(b) To find f(x+7), put x = x+7 in the above expression.

(c) To find f(-x), put x = -x in the above expression.

Hence, this is the required solution.
I believe it would be the first option.
