Answer:
a....12^2+16^2=20^2
Step-by-step explanation:
Okay on what? I would be happy to help you
First in order to solve you need to get rid of the fraction. You can do so by multiplying to entire equation by the denominator like so...
5(5r - 1/5) = (4/5)5
25r - 1 = 4
Then to isolate the variable you need to add 1 to both sides.
25r = 5
Then you divide.
r = 5/25
Simplify.
r = 1/5
I hope this helps love! :)
From the point-slope formula, we have:
where m is the slope, (x_0,y_0) are known points.
In this case, we have the slope and two points, we can substitute in the formula to get:
therefore, a=3
Note: you can also find a if you use the slope formula.
