A high school drama department sold 238 tickets for their performance. o   An adult ticket cost $6.75.
o   A student ticket cost $3.50.
o   The high school drama department collected $1,252.25 in ticket sales.
How many student tickets were sold? 

$6.75 + $3.50 = X

X ÷ $1,252.25

Step-by-step explanation:

$6.75 + $3.50 = $10.25

$10.25 ÷ $1,252.25 = 0.00818526652

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1
