The anwsers are
A.(0,-1)
B.(-2,3)
C(-4,0)
D(0,-4)

  D.   (0, -4)

=========================================================

Explanation:

If you solve for y, you would get . The less than or equal to sign shows we shade below the solid boundary line.

Of the four answer choices mentioned, only (0,-4) is in the shaded region. So this is the only solution.

If we plugged the coordinates into the inequality, we get a true statement as shown below

This is a true statement because -16 is to the left of -8 on the number line. So -16 is smaller.

In contrast, if we tried something like (x,y) = (0,-1), then we see...

Which is not true because -4 is actually larger than -8. Use a number line to see this. So (0,-1) is not a solution. The same can be said about (-2,3) and (-4,0) also.

it's both, now can you answer my most recent question?

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
