He equation y = kx represents a proportional relationship between x and y, where k is the constant of proportionality. for a moving object, the equation d = st represents a proportional relationship between distance (d) and speed (s) or between distance (d) and time (t). explain the different ways that you can define the constant of proportionality for this equation. then describe some other equations that represent proportional relationships in the real world and explain why they’re useful. research on the internet, if needed.

you start with $5 and save $10 a week until you have at least $45wer

step-by-step explanation:

answer:   the paragraph proof is mentioned below.

step-by-step explanation:

given: in a δxwy where

such that, ∠wzx ≅ ∠yzx and zw≅zy

we have to prove that: segment zx is a perpendicular bisector of segment wy.

prove: since, zw≅zy ⇒ ∠wzy is a supplementary angle.

then, ∠wzy= 180°

⇒∠wzx + ∠yzx = 180° ( because xz divides ∠wzy into two parts)

but, ∠wzx ≅ ∠yzx ( given)

⇒∠wzy+∠wzy=180° ( by substitution)

⇒2∠wzy=180°

⇒∠wzy=90°

⇒∠wzy=∠yzx =90°

therefore, xz⊥wy where wz=zy

⇒zx is a perpendicular bisector of wy.
