X^2/100+y^2/25=1 the length of the major axis is: a)5 b)10 c)20

well what did you do it matters what you did : )

step-by-step explanation:

i will u if u answer my question in math

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)
