Answer:
Step-by-step explanation:
In order to write the equation of the line perpendicular to the given line, we first have to know what the slope of the given line is, and there's no way to tell by looking at it in its current form, which is standard. We need to solve that equation for y to determine the slope of that line. Solving for y:
and
3y = 4x - 5 (just change all the signs so our y term isn't negative anymore...yes, you're "allowed" to do that!) and
So we can see now that the slope of this line is 4/3. That means that the perpendicular slope is -3/4. Passing through the given point (3, 5):
* and
and
so
** and, in standard form:
4y = -3x + 29 and
3x + 4y = 29***
* : point-slope form
** : slope-intercept form
*** : standard form

5,500 days or what? I don't get it
Hi!
We know she makes $32,000 a year, but we need to know how much she makes in a week. Which leads us to the question,"How many weeks are in a year?".
There are about 52 weeks in a year.
To found out how much money she makes per week, divide.
money per week
32000/52 = 615.384615
I'm not sure if they want you to round up, or round down, or what, but the exact answer is 615.384615.
Hope this helps! :) -Peredhel
