We have
-2x-3y <12
For this case what you should do is to graph the following straight line:
-2x-3y = 12
Then, the solution will be the shaded region that satisfies the following inequality:
-2x-3y <12
In the shaded region you will find all the solution points.

Answer:
(1.06)0 = 1 and positive powers of 1.06 are larger than 1, thus the minimum value N(t) attains, if t≥0, is 400.
From the point of view of the context, a CD account grows in value over time so with a deposit of $400 the value will never drop to $399.
Answer:

Step-by-step explanation:
Answer:
trapezoid
Step-by-step explanation:
y = 4x slope = 4
y' = 4x -16 slope = 4
TA // OM
TA: -1 ≤ x ≤ 0 (limited value)
OM: 3 ≤ x ≤ 5
TA and OM limited in different range, their length is not equal
The shape is a trapezoid
the equation for compound interest is

we will see if it doubles or not
if t=1, we get A=P(1+r)
if t=2, we get A=P(1+r)^2
2(P(1+r))=P(1+r)^2 ?
2(1+r)=(1+r)^2 ?
2+r=r^2+2r+1
etc
when r=-1.618 or 0.618, then it doubles, but not when r is different things
not always
so no, it does not always double the amount of interest earned
