A $100 per deposit
because it went from 50 to 150
Answer:
Step-by-step explanation:
The slope-intercept formula is:
y = m x + b,
or: y = b - m x, since the rate is negative.
For the 1st formula we have: y = 30 and x = 2
For the 2nd formula: y = 12 and x = 5 ( because: 5 = 2 + 3, or : 3 minutes later, which can be confusing )
30 = b - 2 m
12 = b - 5 m
--------------------
b = 30 + 2 m
12 = 30 + 2 m - 5 m
3 m = 18
m = 18 : 3 = 6
b = 30 + 2 * 6 = 30 + 12 = 42
Answer:
y = 42 - 6 x
3 people wearing both are also counted in the 6 with socks and 4 with shoes so you can't count them twice. What you do in stead is list :
<span>3 wearing both </span>
<span>4 - 3 = 1 wearing just shoes </span>
<span>6 - 3 = 3 wearing just socks </span>
<span>total 7 so far so that leaves 5 others that must be barefoot.</span>
The exponential equation that represents the number of followers y the Miami Marlin’s had x years after they joined the site in 2009 is:

<h3>What is an exponential function?</h3>
An exponential function is modeled by:

In which:
- A(0) is the initial value.
- b is the rate of change, as a decimal.
In this problem:
- In 2011, the Miami Marlins had about 11,000 followers on a social media site. Since 2011 is 2 years after 2009, the point is (2, 11000).
- Using the 2016 data, the point is (7, 240000).
Given two points, the rate of change is given by:


![b = \sqrt[5]{21.818181}](https://tex.z-dn.net/?f=b%20%3D%20%5Csqrt%5B5%5D%7B21.818181%7D)

Then, the equation is:

Point (2, 11000) means that when
, hence this is used to find a.



Hence, the exponential equation is:
