Number of general admission tickets sold is 75
<u>Step-by-step explanation:</u>
Step 1:
Let the number of general admission tickets be x, then the number of student ID tickets = 200 - x. Total cost of tickets sold = $625
Cost of general admission tickets = 5x
Cost of student ID tickets = 2(200 - x) = 400 - 2x
Total cost of tickets = 5x + 400 - 2x = 625
⇒ 3x + 400 = 625
⇒ 3x = 225
⇒ x = 75
Answer:
y = -0.093x^2 - 1.586x + 12.383 is closest to being "true" for a point selected at random from the given table.
Step-by-step explanation:
Eliminate the first and third options immediately, since neither is a quadratic.
Choose any point from those given, such as (4, 7.3). Check out either the second or the fourth option; I'll arbitrarily choose the fourth: y = 0.093x^2 - 1.586x + 12.383.
Subst. 7.3 for y and 4 for x: 7.3 = 0.093(16) - 1.586 (4) + 12.383. Is this true or false?
7.3 = 1.488 - 6.344 + 12.383
7.3 = 1.488 + 6.039
7.3 = 7.527 This is close but still too far off to
be absolutely correct,
Check out the second equation: y = -0.093x^2 - 1.586x + 12.383
7.3 = -1.488 -6.344 + 12.383
7.3 = -7.832 + 12.383
7.3 = -4.551 This is much further off!
Select the fourth equation as being closest to being satisfied by the point (4, 7.3).
Answer:
19
Step-by-step explanation:
f(x)= -3x-2
f(-7)= -3(-7)-2
= 21 - 2
= 19
