X^2 + 8x + 3
= (x + 4)^2 - 16 + 3
= (x + 4)^2 - 13 Answer.
You divide the + 8 by 2 to get the +4 and you then subtract 4^2 ( which is the -16).
I'm not sure about 1 and 2 but 6 is wrong it is a = sign and 7 is wrong.
Answer:
A
Step-by-step explanation:
all we need to do is to plug the point (6,4) in the inequality and see if it satisfies it :
pay attention that here we have x=6 y=4
4<
we simplify we get :
4<4.5-3
4<1.5 which is incorrect so (6,4) is not a solution. moreover
notice that 4 is > than 1.5 so the point lies above the line
thus the answer is : A
you can also solve this problem by graphing the line and plotting the point (6,4) and hence you will notice that the point is above the line
