Answer:
-3 < x
Step-by-step explanation:
15 > -5x
Divide each side by -5, remembering to flip the inequality since we are dividing by a negative
15/-5 < -5x/-5
-3 < x
(x + 12) = (x + 14) - 3
subtract 12 from each side
x = x + 14 - 3 - 12
Now if we subtract x from each side we see that x - x = 0. Combine the terms left over and we have -1, so
0 = -1
The answer is NO SOLUTION
Answer:
C
Step-by-step explanation:
A models an exponentially increasing function.
B models an exponentially decreasing function.
C models a "bell" curve, similar to the one shown.
D models a "logistic" function, an s-shaped curve that smoothly transitions between two horizontal asymptotes.
Writing an equation is the easiest way to figure this out.
