Answer:
Step-by-step explanation:
- The freight elevator can hold a maximum weight of 3500 pounds
- The delivery man weighs 200 pounds
- Each carton weighs 48 pounds
Let the number of cartons he can safely put on the elevator at one time=n
Total weight of Carton=48n
Since the weight of the man and the cartons combined must not be more than 3500 pounds,
Therefore,an inequality that represents the situation is:
We can solve for n if required
The delivery man can safely carry 66 Cartons.
We have the following function:
So if we graph this function we will get the Figure below. Thus, let's study both the equation and the graph to get some conclusions. Therefore, we can assure these statements:
First. The function is defined only for
as shown in the Figure. This is also true because of
where
must be greater (or equal) than zero.
Second. The range of the function are the values of
.
Third. If
creases then
always creases, too.
Answer:
what problem??
Step-by-step explanation:
Mr. Jackson invested $800 at 6% per year and $ 2400 at 4 % per year
<h3><u>Solution:</u></h3>
Mr. Jackson invested a sum of money at 6% per year, and 3 times as much at 4% per year.
Let the sum invested be ‘a’ and ‘3a’ at 6% per year and 4 % per year respectively
Also, his annual return totaled $144
We can form following equation on the basis of question:-
a = $800
The amount of money invested at 6% = a = 800
The amount of money invested at 4 % = 3a = 3(800) = 2400
So, the amount of money invested at 6% is $800 and the amount of money invested at 4% is $ 2400
