Answer: 2

Step-by-step explanation:

The question is asking you to substitute the b with 4 and find the solution to the expression.

\frac{1}{2}b^{2} -6

=\frac{1}{2}(4)^{2} -6

=\frac{1}{2}(16) -6 (PEMDAS so you do the exponent first)

=8 -6 (PEMDAS so you do the multiplication first)

=2

Please I will rate you with 5 stars just please help me with this problem
olchik [2.2K]

Answer:

D

Step-by-step explanation:

If we isolate the variable in each given compound inequality, we can quickly realize that D is correct.

16\geq 3x+4>1\\12\geq 3x>-3\\4\geq x>-1

x is less than or equal to four (solid point on 4 with line going left), but greater than -1 (open point going right).

Signs with 'or equal to' have solid points, and signs without are not solid.

I hope this helps!
