Graph the function defined by f(x)= |-x-7|
1 answer:
Answer: The answer is the third graph, attached herewith the image.
Step-by-step explanation: The given function is
We are to select the correct graph from the given four options that is defined by the function above.
At x = 0, y = 7
and
at y = -7, y = 0.
So, the points (0, 7) and (-7, 0) satisfies the given function and hence these points must lie on the graph also.
We can see that the points (0, 7) and (-7, 0) lie only on the third graph. The image is attached with these two points plotted.
Thus, the answer is the third graph.

Answer:
Percentage score will be 83.33 %
Step-by-step explanation:
We have given Antonette gets 70 % on 10 problem test
Let consider here here total problem = total marks
So marks get 10 10 problem test = 10×0.7 = 7
Marks get in 20 problem test = 20×0.8 = 16
And marks get in 30 problem test = 30×0.9 = 27
Now total marks get get by Antonette = 7 +16 + 27 = 50
And total marks = 60
So percentage score of Antonette %
