On a certain map, 1 centimeter represents 5 kilometers. on the map, region x has an area of 6.4 square centimeters.
quantity a quantity b
the actual area of region x 150 square kilometers
a) the quantity in column a is greater.
b) the quantity in column b is greater.
c) the two quantities are equal.
d) the relationship cannot be determined from the information given.

see below

step-by-step explanation:

x+2> 6

subtract 2 from each side

x+2-2 > 6-2

x > 4

there is an open circle at 4 since is it is greater than and the line goes to the right

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)
