Answer:

square root of 10

Step-by-step explanation:

a^2 + b^2 = c^2

=> a^2 + 9^2 = square root of 91^2

=> a^2 + 81 = 91

=> a^2 = 91 - 81

=> a^2 = 10

=> a = square root of 10

A point at (4,6) is reflected across the x-axis.What is the y-coordinate of the reflected point?
iren [92.7K]
I believe the ansr would be (-6,-4) I say this becuase if it's positive on the y axis the X axis will be negative and if it's being reflected the coordinates will be backwards. If this answer is wrong I'm truly sorry, but I hope this helps!
