You can put this solution on YOUR website!Here's an example. Email me if you like.
--------------------
A line and a point example.
Write in standard form the eqation of a line that satisfies the given conditions. Perpendicular to 9x+3y=36, through (1,2)
-----------------
Find the slope of the line. Do that by putting the equation in slope-intercept form, y = mx + b. That means solve for y.
9x+3y = 36
3y= - 9x + 36
y = -3x + 12
The slope, m = -3
------------------
The slope of lines parallel is the same.
The slope of lines perpendicular is the negative inverse, m = +1/3
----------------
Use y = mx + b and the point (1,2) to find b.
2 = (1/3)*1 + b
b = 5/3
The equation is y = (1/3)x + 5/3 (slope-intercept form)
x - 3y = -5 (standard form)

You can put this solution on YOUR website!f(x)= 2x-3
g(x)= x^2+1
Solve f/g (not solve, but find or calculate.)
So I set the equation (2x-3)/(x^2+1)
That's not an equation, there's no equal sign.
-------------------
Where do you go from here?
Nowhere, that's all that can be done.

Can you please show me the steps to solve this equation?
It's not an equation, so there's nothing to solve. You're done.

--------------
3 miles in 12 minutes = 15 mph
3 miles in 18 minutes = 10 mph
His rowing speed is the average = (15+10)/2 = 12.5 mph
The current speed is the difference = 15 - 12.5 = 2.5 mph
