which statements about h′ are true?

select each correct answer.

the y-coordinate is −1.
the y-coordinate is 1.
the x-coordinate is −9.
the x-coordinate is 9.

Answer

The y-coordinate is -1 and the x-coordinate is 9

Explanation

A reflection is a folding where the resulting object will have same shape and size. An object reflected on the x-axis will have its x-coordinate remaining the same , where as the y-coordinate gaining a negative sign. This is to mean that the reflection of a point (x,y) across the x-axis forms a point (x,-y).

true. earthquakes are felt whenever there is a slip around a fault in the rocks below the earth. this reorientation of faults create sesmic waves and is known as earthquake, the severity of which is measured in richter scale. these are more prominent in hilly regions as the rocks usually form faults to balance the pressures on it.
