Dy/dx=1/2, 1/2, 1/2 etc

So this is a linear equation of the form y=mx+b where m=dy/dx=1/2 so

y=x/2 +b, now we can use any point to solve for the y-intercept, "b", I'll use (7,0)

0=7/2 +b

b=-7/2 so

y=x/2-7/2

y=(x-7)/2

Oranges cost $1.79 a pound. Miguel bought 3.6 pounds of oranges. How much did the oranges cost, to the nearest cent?

hammer [34]

Answer: 644cents

Step-by-step explanation:

From the question, we were told that

1 pound = $1.79

Miguel bought 3.6 pounds of oranges. This will cost

$1.79 x 3.6 = $6.444

Recall:

$1 = 100cents.

Therefore, $6.444 = 6.444 x 100 = 644.4cents = 644cents. To the nearest cent

At a rate of 36 miles per hour, it takes Henry 15 minutes to drive from the library to his house. Show how to find the distance

EastWind [94]

This is applying the formula
$distance=rate*time$

We have a slight problem, though, because we are measuring rate in miles per hour, and we are measuring time in minutes. To make this problem solvable, we need to convert to either miles per minute or convert the time to hours. I'm going to convert the 15 minutes into hours:
$15min*\frac{1 hour}{60 min}=\frac{1}{4}hour$

Now that all of the units match, we have:
$distance=36\frac{mi}{hr}*\frac{1}{4}hr$

You can finish from there I'm sure.
