PLSSS HELP WILL MARK BRAINLIEST! (reflections) Quadrilateral PQRS is located in the first quadrant of a coordinate plane. One of its vertices, P, is located at (1, 7). If the quadrilateral is reflected across the y-axis, what is the location of point P'?

(-7, 1)
(7, -1)
(1, -7)
(-1, 7)

Option 4

Step-by-step explanation:

If we're reflecting across the y-axis, then the the y value of the point will remain the same.  The only option that displays this is option 4.

Ah, the power of multiple choice elimination.

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.
