Answer:

Step-by-step explanation:

just put the x and y values into the equations and see which equation stays true.

for example, point (4, 68) rules out A and C even without detailed calculation, because these 2 expressions can produce for positive x only negative y (and 68 is clearly a positive y).

so, when using this point in B :

68 = 4×4² + 2×4 - 4 = 4×16 + 8 - 4 = 64 + 8 - 4 = 68

correct.

and it is correct also for the other points.

so, B is the right answer.

Answer:

Step-by-step explanation:

4x+6<= -54

4x <= -60

x <= -15 [The point -15 is included, so it must be a solid dot]

----------------

5x + 7 > -18

5x > -25

x > -5 [The point -5 is NOT included, so it should be an empty dot.]

Solution C seems the best.
