0.6n = n + 31.8
0.6n - n = 31.8
-0.4n = 31.8
n = 31.8 / -0.4
n = -79.5

Answer:
x≥-8
Step-by-step explanation:
domain of f(x) :
9(x+8)≥0
x+8≥0
x≥-8
Answer:
A. (1, 0)
Reason:
When the first equation is graphed: y <u><</u> x + 1, the left side of the line is shaded and when the second equation is graphed: y <u><</u> x^2 -3x, the bottom is shaded.
The green section does not contain solutions. So D is automatically out.
The red section does not contain solutions as well. So C is automatically out.
For choice B, the point goes out of the shaded blue section, so that's out also.
As for choice A its in the blue shaded section, which makes that answer correct.
(when the two equations are within each other and combine a color, then whatever points is within the shaded part is the right answer)
since it travel at a constant speed. Calculate first its
speed of descent.
S = -3/4 mile / 1 ½ hr
S = -0.5 mile an hour
So the position of the diving bell relative to sea level 1
hour after it began its descent is
D = (0.5 mile/ hr) x 1 hr = - 0.5 mile
