10 points, easy question johnny reflects ∆abc across the y axis and then again across the x axis. hallie rotates ∆abc 180° clockwise about the origin. sally says the resulting images will have the same coordinates. true? or false?

TRUE

Step-by-step explanation

reflection across the y-axis changes the sign of the x-coordinate

reflection across the x-axis changes the sign of the y-coordinate

reflection 180° about the origin changes the signs of both the x- and y-coordinates.

Johnny: (x, y) → (-x, y) → (-x, -y)

Hallie: (x, y) → (-x, -y)

you need to give us more information since we can't answer

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.
