Agroup of friends are going to see a movie. the admission cost is $8 per person. the table below represents the number of friends and the total cost. movie costs number of friends, (x) 2 3 4 5 total cost in dollars, (y) a-(2, 10), (3, 11), (4, 12), (5, 13) b-(2, 16), (3, 24), (4, 32), (5, 40) c-(10, 2), (11, 3), (12, 4), (13, 5) d-(16, 2), (24, 3), (32, 4), (40, 5)

B-(2, 16), (3, 24), (4, 32), (5, 40)

Step-by-step explanation:

Given,

x represents the number of friends and y represents the total cost in dollars,

Admission cost of one person = $ 8,

⇒ Admission cost of x persons = 8x

⇒ y = 8x

Which is the equation that represents the given situation,

If x = 2, y = 16,

If x = 3, y = 24,

If x = 4, y = 32,

If x = 5, y = 40,

Thus, the set of ordered pairs of that can be written from the table are,

(2, 16), (3, 24), (4,32) and (5, 40),

Option B is correct.

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3
