Answer:
1. B. a=14, b=2
2. D. a=1, b=1.4
Step-by-step explanation:
The exponential growth function can be represented as

where b is the growth factor.
1. When the function has equation

then

The initial amount is the value of the function at x=0:

The growth factor is b=2
2. When the function has equation

then

The initial amount is the value of the function at t=0:

The growth factor is b=1.4
Answer:
4,0
Step-by-step explanation:
The Y-intercept is always a number then a zero
a = adult ticket price
s = student ticket price

7a + 2s = 87
---
4a + 6s = 74
4a = 74 - 6s
a = 74/4 - (6/4)s
a = 37/2 - (3/2)s
---
7a + 2s = 87
7(37/2 - (3/2)s) + 2s = 87
7(37/2) - 7(3/2)s + 2s = 87
(259/2) - (21/2)s + 2s = 87
(21/2)s - 2s = (259/2) - 87
(21/2)s - (4/2)s = 259/2 - 174/2
(17/2)s = 85/2
---
s = 85/2(2/17)
s = 85/17
---
Answer:
s = $5
a = $11
---
Division property of equality, because you have to divide 8x and 80 by 10
