Answer:
a>4
Step-by-step explanation:
-7a-11<1-4a
ADD 4a to both sides
-3a-11 <1
Add 11 to both sides
-3a <12
Divide both sides by 3
-a <4
Multiply by -1 both sides and FLIP SIGN
a>4
So a should be 5 ,6,7,8.........
On the number line you need to count from zero 4 units to the right (positive 4) Once you are in number 4 draw an open circle which means the 4 is NOT included) Draw a line from 4 to the right because it is bigger than 4.
Interval notation is (4,∞)
[ ] a square bracket when we want to include the number 4
( ) a round bracket when we don't want to include the number 4

Answer:
C
Step-by-step explanation:
factorizing 24:
factors of 24 : 1, 2, 3, 4, 6, 8, 12
looking at your answer choices, we can see that 5 and 7 are not factors of 24, so we can immediately eliminate a and b.
we also see that answer c does indeed contain factors of 24 and they both add to 10. So c is the answer.
It is not a function because x repeats
Domain={1,-2,-1}
Range={-2,0,2,3}
Hope this helps
Have a great day/night
