Step-by-step explanation:
The slope of the equation tangent to y = f(x) at x = 4 is equal to f'(4). Therefore,

We also know that the line passes through the tangent point at (4, -1) so we can write the slope-intercept form of the equation as
or

so our equation is

or in standard form,

Yes.
Answer: Please include more information
Step-by-step explanation:
Let the two segments be x and y
x+y=45...1
X/y = 2/3...2
From1, y=45-x
Sub this into 2
x/(45-x)=2/3
3x=90-2X
5x=90
x=18
y=45-18=27
