A discount airline sells a certain number of tickets, ,
for a flight for $90 each. It sells the number of
remaining tickets, y, for $250 each. For a particular
flight, the airline sold 120 tickets and collected a total
of $27,600 from the sale of those tickets. Which
system of equations represents this relationship
between x and y?

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )

i am unable to solve this problem

step-by-step explanation:

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.
