H(x) = 16 - x
plug -4 in as x
H(x) = 16 - (-4)
solve 16 - (-4)
H(x) = 20
your answer is A)20
Negative because if you take away from a negative, your just making it smaller... hope this helps!

Answer:
About 947 hours, walking at 5 km (3 miles)/hour.
Walking 8 hours /day [at that pace you would need to be an Olympic Athlete to keep up the pace] it will take about four months.
Walk slower, it will take longer.
<span>-16x^3+4x=0
-4x(4x^2 - 1) = 0
-4x(2x+1)(2x - 1) = 0 (factor using a^2 - b^2 = (a+b)(a-b))
-4x = 0; x =0
2x +1 = 0;x = -1/2
2x - 1 =0; x = 1/2
answer: x = 0, x = 1/2 and x = -1/2</span>
