The graph adequately represents the following case
"The number of employees at a store increased at a constant rate for 5 years. There was a decrease in the number of employees for 2 years. Then the number of employees increased at a greater constant rate for the next few years."
Step-by-step explanation:
To solve the above-mentioned problems we need to filter the results through analysing the options given-
We have to keep in mind that-
- For an increase in value/quantity- the graph would be on an upswing
- For decrease in value/quantity- The graph would be in declining mode
- For constant value- horizontal graph line parallel to the x-axis
Now going through the options-
option 1:-
David drove at a constant speed initially- throughout the graph no horizontal line is present, hence this condition does not represent the graph.
option 2:-
test scores increased and then decline- In this condition only two phases are mentioned, whereas in the graph three different phases are present. Hence this condition too does not represent the graph.
option 3:-
After the period of slow.- The graph starts with an upswing. hence this condition too does not represent the graph.
option 4:-
Employees increased and then declined and then again increased. All the above condition corroborates to the above-mentioned graph. hence this condition is represented in the graph
There are two triangles here: ABC and ADF. These triangles are similar, and thus proportional. So, we can set up a proportion between the left side of each triangle and the base of each triangle.
AB / AD = BC / DE
4 / (4 + BD) = 5 / 9
---AD is made up of AB and DB. We know AB, but not BD, so we need to find its value to find the length of AD.
5(4 + BD) = 9 x 4
20 + 5BD = 36
5BD = 16
BD = 3.2
AD = AB + BD
AD = 4 + 3.2
AD = 7.2
Hope this helps!
Answer
2x-9
Step-by-step explanation:
Answer:
I think the answer is D
if we use this equation to find the slope ( slope= Y2-Y1/X2-X1)
6-3= 3
2-1=1
so then you divide it and you get 3/1 or 3
