Answer: Hence, Option (6) and (8) are correct as their value is also "-8".
Step-by-step explanation:
Since we have given that
First we need to solve to get the value of 'x' :
Therefore, x=-8
Now, we will check all the options :
1) 4x+8=24
2) 9x+18=-24
3) 4x+12=-24
4) 18x+36/2=-24
5) 4x=-36
6) 4x=-32
7) x=-9
8) x=-8
Hence, Option (6) and (8) are correct as their value is also "-8".
Average rate of change=slope
f(x)=x-5
f(x) could be subsitututed with y so
y=x-5
this is in y=mx+b form where m=slope and b=y-intercept
y=1x-5
slope=1
average rate of change=1/1
if x=-2 then
y=-2-5
y=-7
if x=1 then
y=1-5
y=-4
the graph of y=x-5 is included in the attachment
