You get: (1x20)/(5x20)=20/100=20%.
Hope i helped you! :)
For both lines the slope is 5/2 or 2.5.
Since the y-intercept is zero for both, both the equations are:
y=2.5x
Or
y=5/2x
31252130405 is the answer :)
we know that
If
is a factor of the function 
then
is a root of the function f(x)
therefore
For
the value of the function must be zero
Verify
Substitute the value of
in the function





therefore
<u>the answer is</u>
Yes,
is a factor of the function f(x)
