Use the functions f(x) = 4x − 5 and g(x) = 3x + 9 to complete the function operations listed below. Part A: Find (f + g)(x). Sho
Bingel [31]
Part a)
16 x - 10
f + g = 5x − 12 + 11x + 2= 16x -10
Part b)
f * g = (5x − 12)(11x + 2) = 55x^2 - 132x + 10x - 24 =  55 x^2  - 122 x - 24
<span>Part c) </span>
<span>f(g(x)) = f( 11x + 2) = 5(11x +2) - 12 = 55x + 10 - 12 = 55x-2

Please help I will give thank 5 stars 50 points and make brainliest
Alexandra [31]
Part A= the starting point is in quadrant 2 and the finishing point is in quadrant 4
is say this because the starting points X and Y value is Neg,Pos there is only one quadrant that has Neg X and Pos Y and that is quadrant 2 and for the finishing point its X and Y value is Pos,Neg and there is only one quadrant that has Pos X and Neg Y and that is quadrant 4 

Part A=starting point at quadrant 2 and finishing point at quadrant 4 explanation is above.

Part B= the starting point and the are checkpoint have the same Y and opposite but same X they are equally far form 0 but relative to the finishing point the checkpoint is closer by 2 units on the X axis and the starting point is farther by 2 units on the X axis

The sum of the interior angles of Michael’s polygon equals 180°. The sum of the interior angles of Cary’s polygon equals 360°. H
Lady_Fox [76]
Recall that for a polygon to have 180° as the sum of its interior angles, then it must have three sides and thus a triangle. And similarly, for a polygon to have a sum of 360°, it must have four sides or it is a quadrilateral.

[Note that for larger angles, we can apply the formula 180(n - 2) to find the total sum of the interior angles. n is the number of sides]

Now, since we're comparing a four-sided and three-sided polygon, this means that they only differ by 1 side. 

Answer: A. 1 side
