The answer is 7

If it took him 18 days to ride 360 miles find the average it took home each day (360/18= 20)

Then minus 360 from 500 miles to find how many miles Miguel has to still run.

Finally, divide the remaining miles by the average by how many miles he can run each day and you get the answer (140/20=7)

The difference between a number and 17 is 96. Find the number
jeka57 [31]

Answer:

The number is 79

Step-by-step explanation:

Let the number be 'x'

x + 17 = 96

Subtract 17 from both sides,

  x + 17 -17 = 96 - 17

<h3>           x = 79</h3>

Find all values of m so that the function y= e^mx is a solution of the given differential equation.
son4ous [18]

Answer:

m = - 2 is the value of m that the function y= e^mx is a solution of the differential equation, y' + 2y = 0.

Step-by-step explanation:

To determine all values of m so that the function y= e^mx is a solution of the given differential equation.

First, we will find y'.

From, y= e^mx

y = e^{mx}

But, y' = \frac{d}{dx}y

Hence,

y' = \frac{d}{dx}e^{mx}\\

∴ y' = me^{mx}

Now, we will put the values of y' and y into the given differential equation y' + 2y =0

From the question,

y = e^{mx}

and

y' = me^{mx}

Then, y' + 2y =0\\ becomes

me^{mx} + 2(e^{mx}) = 0

Then, me^{mx} = - 2(e^{mx}) \\\\

m = \frac{-2(e^{mx}) }{e^{mx} } \\

∴ m = -2

Hence, m = - 2 is the value of m that the function y= e^mx is a solution of the differential equation, y' + 2y = 0.
