Two congruent figures, A and B, are shown on a coordinate plane below. Ay
V
Which of these reflection(s) map figure A onto figure B?
a reflection over the line y
a reflection over the line y--
a reflection over the line xo followed by a reflection over the line x = 0
a reflection over the line xo followed by a reflection over the line y = 0

A reflection over the line x=0 followed by a reflection over the line y=0

Step-by-step explanation:

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
