I'll do f+g, you try the others on your own and comment if you need help with them! For f+g, you're just going to add the two functions together:
f(x)=3x+7
g(x)=x+9
(f+g)(x)=(3x+7)+(x+9)=4x+16

Please answer this worth 10 points<br><br> look in the image plz
Pachacha [2.7K]
1) It’s true because -5 is way smaller than 3. All the negatives are below the 0 and everything below the 0 is lower than everything above the 0.

2) false. it’s false because in order -5 isn’t even close to 3

3) false.. It’s false because when you have those 2 line that are covering the -5 that means it’s “transforming” into a positive number. So therefore it’s would be 5>3 that would make it true.

4) True. it’s true because like I said the to lines mean the absolute value of something. So it’s being switch to a positive number


Hope this helps :)

Ad libitum [116K]
<span>I have graphed the given coordinates of both pentagons. The reflection was across the y-axis where coordinates of Pentagon PQRST (-x,y) resulted to Pentagon P'Q'R'S'T' (x,y). The line of reflection between the pentagons was x = 0. Line of reflection is the midway between the pre-image and its reflection.</span>

Don’t take my word for it but if there’s no x then it might be undefined.
Sorry if I’m incorrect
