The 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.

144.50

step-by-step explanation:

21.5 x 13.4=288.10 divide by 2

answer:   x*94 +688*6   = 267*100

94x+4128=26700    

94x=22572     /94

x=240.128

step-by-step explanation: mark as brainlest reallly need it thx

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)
