Answer: The least number of minutes that he has used his phone in a month is 1248
Step-by-step explanation:
Let m represent the number of minutes that he used his phone in a month.
For his phone service, Michael pays a monthly fee of $16, and he pays an additional $0.04 per minute if use. This means that if he used m minutes in a month, the total cost would be
16 + 0.04m
The least he has been charged in a month is $69.52. This means that
16 + 0.04m ≥ 65.92
0.04m ≥ 65.92 - 16
0.04m ≥ 49.92
m ≥ 49.92/0.04
m ≥ 1248 minutes

Answer:
The first number should be a number between 1 and 10 (see explanation)
Step-by-step explanation:
For a number to be in scientific notation, a number between 1 and 10 has to be multiplied by a power of 10.
36.5 is not between 1 and 10, alternatively, you can rearrange it:
3.65 x 10^7 <----This would be the correct scientific notation

<h2>Answer</h2>

<h2>Explanation</h2>
The first thing we need to do is find the slope of our line. To do it we are using the slope formula:

where
is the slope of the line
are the coordinates of the first point on the line
are the coordinates of the second point
From our graph we can get the points (0, 43) and (2, 55), so
,
,
, and
. Let's replace the values in our slope formula:



Now that we have our slope, we can use the point-slope formula:



But remember that the equation of a line in standard form is
, so we need to subtract
and add 43 to both sides of our point slope equation:



We can conclude that the equation in standard form that represent the relationship in the graph is
.
