Answer:
The amaryllis that grows 18 inches in one week
Step-by-step explanation:
Solve each of the equations independently, then determine if the are continuous or discontinuous.
15≥-3x [start here]
-5≤x [divide both sides by (-3). *Dividing by a negative number means the direction of the sign changes!]
x≥-5 [just turned around for analysis]
Next equation:
2/3x≥-2 [start here]
x≥-2(3/2) [multiply both sides of the equation by the reciprocal, 3/2)
x≥-3
So, (according to the first equation) all values of x must be greater than, or equal to -5.
(According to the second equation) all values of x must be greater than, or equal to -3.
So, when graphed on a number line, both equations graph in the same direction, so they are continuous.
Answer:
18 weeks
Step-by-step explanation:
Initial amount stored in savings account = $700
Final minimum amount required in the account = $150.
Thus,
The total amount of money he can spend = (700 - 150) = $550
Each week he is withdrawing $30 to go out to eat.
Since , maximum money he can spend should be multiple of 30 ,
Thus maximum he can spend $540
number of weeks he can do this = 
= 18.
So, he can take out $30 each week to go out to eat for 18 weeks only.
