Basically the question is asking to solve for x if a is negative.
So to do this, simply change the sign for a to -a in the original equation and solve for x.
-ax > -12
X < 12/a.
This is the solution.
Answer:
The z-scores for which 3% of the distribution's area lies between -z and z is z=0.03761.
Step-by-step explanation:
We have to find the z-score z* for which the following condition is satisfied:
This means that half of the area is at the left of the mean and half is at the right, so we have:
Then, we have:
Answer:
x-3/8=3/4, (do inverse operation)x-3/8=6/8, x= 9/8
Step-by-step explanation:
Since the value 0.98 is less than 1, we can therefore say that balance in this account is decreasing.

How to recognize Exponential Function.</h3>
Exponential Function can be used for increase rate and also for decay rate. The difference between the two are the plus and minus signs. To put it in another perspective, If Y = P(M)³
If M is less than one, that means it is decaying or decreasing. And if M is greater than one, that means it is increasing.
Given that Some banks charge a fee on savings accounts that are left inactive for an extended period of time. And the equation
y = 5000(0.98)^x represents the value, y, of one account that was left inactive for a period of x years.
According to the equation, to know if the balance in this account is increasing or decreasing, we will analyze the value 0.98.
Since the value 0.98 is less than 1, we can therefore say that balance in this account is decreasing.

1) would be 2 boxes because the room is 25 ft²
2) $99.50 if you do 25 x 3.98, or if they want 40 x 3.98 it would be $159.20
