We know that there are 60 minutes in an hour, so to get the ratio to equal terms, we could multiply 60 by 3 to find the number of minutes in 3 hours, which is 90. Now the ratio is 17 minutes to 90 minutes. I'm pretty sure this is the lowest terms, but if they want you to convert it to seconds or something, you would multiply 17 by 60 for the first number and 90 by 60 for the second number. Hope this helps!
The format of a line equation is y = mx + b
When two lines are parallel, their 'm' variables are equal.
Knowing this, the unknown line equation, so far, would look like this:
y = 9x + b
Since we know that the line equation goes through the point (2, 7)
7 = 18 + b
b = -11
y = 9x - 11
Answer:
or
Step-by-step explanation:
We are going to see if the exponential curve is of the form:
, (
).
If you are given the 
intercept, then 
is easy to find.
It is just the coordinate of the intercept is your value for .
(Why? The intercept happens when 
. Replacing 
with 0 gives 
. This says when 
.)
So 
.
So our function so far looks like this:
Now to find 
we need another point. We have two more points. So we will find using one of them and verify for our resulting equation works for the other.
Let's do this.
We are given 
is a point on our curve.
So when 
, 
.
Divide both sides by 8:
Reduce the fraction:
So the equation if it works out for the other point given is:
Let's try it. So the last point given that we need to satisfy is 
.
This says when 
, 
.
Let's replace with 2 and see what we get for 
:
So we are good. We have found an equation satisfying all 3 points given.
The equation is .
