12.74 is the answer to the question
<h2>
Hello!</h2>
The answer is:
Garyn would plant the garden by himself in 6 hours.
<h2>Why?</h2>
From the statement, we know that Frankie can plant a garden by herself in 10 hours, but with her son's help(Garyn), they are able to do it in 4 hours.
If they are able to do the work in just 4 hours, it means that that they are able to do it in 6 hours less than Frankie working alone.
Then, let be 10 hours, the Frankie's rate "x" and the Garyn's rate "y", so:
If x is equal to 10:
So, Garyn would plant the garden by himself in 6 hours.
Have a nice day!

Some things you need to know:
1) You need to know how to convert standard form to slope y-int. form and slope y-int. form to standard form.
2) When two lines are parallel, the slopes are the same.
3) When two lines are perpendicular, the slopes are negative reciprocals of each other. (Or their product is -1)
example: 3/4 --> -4/3.
3/4 * -4/3 = -12/12 = -1
4) To find the value of b, substitute the point into the equation.
5) Convert the equation to slope y-int. form to find the slope.
6) When a line has an undefined slope, the slope y-int. will look either like
y = __ (forms horizontal line) or x = __ (forms vertical line).
To find the perpendicular of these lines, turn y to x / x to y.
To find the value of __, look at the point located in the line, so if x = ___
passes through (5,3), then x = 5 because x = 5 in the point. So the
equation would be x = 5.

Answer:
Perpendicular
Step-by-step explanation:
Linear equations will describe parallel lines when the lines have the same slope. These equations are written in slope-intercept form, so we can easily determine that the slopes are ...
f(x): slope is 5/6
g(x): slope is -6/5
These are not the same, so the lines are not parallel.
__
The lines will be perpendicular when the product of their slopes is -1. Here, that product is ...
(5/6)(-6/5) = -30/30 = -1
These equations describe lines that are perpendicular.
