Answer:
The 2nd and last options.
Step-by-step explanation:
By looking at the table we know that the 2nd one is an answer for sure.
Also by looking at the table we know that the 3rd and 4th are not true.
put in -1/2 in the function to see if you get -2
1/2(-1/2)+3/2
-1/4+3/2
-1/4+6/4
5/4
So The first one doesn't work either.
Now the last one:
1/2(4)+3/2
4/2+3/2
7/2
So the last one works too.
Hope this helps :)
(Answer included in imagine)
334/5, or if you want it as a decimal, 66.8
5(x-4)+3x-9x+7
mutiply the bracket by 5
(5)(x)= 5x
(5)(-4)= -20
5x-20+3x-9x+7
5x+3x-9x-20+7 ( combine like terms)
do 5x+3x first
5x+3x= 8x
8x-9x-20+7
8x-9x= -x
-20+7=-13
answer:
-x-13 or -13-x
Change in y over the change in x
