A pair of telephone poles is supported by two cables. A cable line runs from the top of each pole to the bottom of the other. If one pole is 20 m high and the other pole is 30 m high, how high above the ground do the cables intersect?

r = 78539458390583095803458309458039485093485 or just 3

step-by-step explanation:

step-by-step explanation:

total income = price of one ticket   *   number of tickets sold

  y                 =     4                                   x

so the equation is y=4x     with x≥0   because number of tickets sold can not be negative

thus the equation is a semi -line with an end point at

(0,0)

passing through :

x=1     y=4(1) = 4   so through (1,4)

13,000
