If ABCDE is reflected across the line y=-1, then reflected again across they axis, what are the new coordinates of point B?
E.
•B
o
*C
O A. (-4,-2)
O B. (-4,-4)
O C. (6,2)
OD. (-6,-2)

B (-4,-4)

Step-by-step explanation:

B

Step-by-step explanation:

Since it is currently at (4,2), reflecting it across y=-1 will bring the y-coordinate down to -4. After that, reflecting it across the y-axis will flip the sign in front of the x-coordinate, so 4 to -4. Therefore, your answer is (-4,-4).

answer is:

1.75 pounds

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
