Quadrilateral GHIJ is dilated by a scale factor of 2 to form quadrilateral G'H'T'J'. What is the measure of side GH?

b, 20 yards

step-by-step explanation:

you can use a^2+ b^2=c^2

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)
