3 0

Answer:

  • A, B, E

Step-by-step explanation:

<u>Given equation</u>

  • y = 8.5x

<u>Answer choices</u>

A. The equation represents a proportional relationship.

  • TRUE, it is in the form of y = kx

B. The unit rate of change of y with respect to x is 8.5

  • TRUE, y = mx + b, the slope m = 8.5 is the rate of change

C. The slope of the line is 2/17

  • False, the slope is 8.5

D. A change of 17 units in x results in a change of 2 units in y.

  • False, a change of x = 17 results in 17*8.5 = 144.5 units in y

E. A change of 4 units in x results in a change of 34 units in y.

  • TRUE, because 4*8.5 = 34

Exercise 1:
 
exponential decay:
 The function is given by:
 y = A (b) ^ ((1/3) * t)
 Where,
 A = 600
 We look for b:
 (480/600) * (100) = 80%
 b = 0.8
 Substituting:
 y = 600 * (0.8) ^ ((1/3) * t)
 We check for t = 6
 y = 600 * (0.8) ^ ((1/3) * 6)
 y = 384
 Answer:
 
exponential decay:
 
y = 600 * (0.8) ^ ((1/3) * t)
 Exercise 2:
 
linear:
 The function is given by:
 y = ax + b
 Where,
 a = -60 / 2 = -30
 b = 400
 Substituting we have:
 y = -30 * x + 400
 We check for x = 4
 y = -30 * 4 + 400
 y = 280
 Answer:
 
linear:
 
y = -30 * x + 400
 Exercise 3:
 
exponential growth:
 The function is given by:
 y = A (b) ^ ((1/3) * t)
 Where,
 A = 512
 We look for b:
 (768/512) * (100) = 150%
 b = 1.5
 Substituting:
 y = 512 * (1.5) ^ ((1/2) * t)
 We check for t = 4
 y = 512 * (1.5) ^ ((1/2) * 4)
 y = 1152
 Answer:
 
exponential growth:
 
y = 512 * (1.5) ^ ((1/2) * t)

Tickets to a school play cost $3 for students and $8 for adults. On opening night, $1000 was collected and 150 tickets sold. How
vesna_86 [32]
Let the number of students who bought tickets be s,
Let the number of adults who bought tickets be a,

Equation 1:

3s \: + \: 8a \: = \: 1000

Equation 2:

s \: + \: a \: = \: 150 \\ s \: = \: 150 \: - \: a

Substitute ( 2 ) into ( 1 ),

3(150 \: - \: a) \: + \: 8a \: = \: 1000 \\ 450 \: - \: 3a \: + \: 8a \: = \: 1000 \\ 5a \: = \: 550 \\ a \: = \: 110

Substitute a = 110 into ( 2 ),

s \: + \: 110 \: = \: 150 \\ s \: = \: 40

Ans: 40 Student Tickets, 110 Adult Tickets
