It would help to know which side is B, can you give a chart?
And I'm on my phone, I can't comment directly on the post, unless someone can tell me how.
Answer:
x=3 , x=-3
Step-by-step explanation:
Add 9 on both sides
To remove base 'e' we take ln on both sides
Both sides have ln , so we make the terms equal
Take square root on both sides
x=3 , x=-3
This means an initial fee of $45 have to be paid to the provider and a charge of $35 per month.
<h3>
Linear equation</h3>
A linear equation is in the form:
y = mx + b
Where y, x are variables, m is the rate of change and b is the initial value of y.
Let S represent the total cost of service for x months. Given:
y = 35x + 45
This means an initial fee of $45 have to be paid to the provider and a charge of $35 per month.

Answer:
speed of the boat = 100 mph
Step-by-step explanation:
Let x = speed of the boat
upstream speed = x - 4
downstream speed = x + 4
time = 24/(x - 4) = 26/(x + 4)
Cross multiply:
24(x + 4) = 26(x - 4)
24x + 96 = 26x - 104
104 + 96 = 26x - 24x
200 = 2x
x = 100 mph
