Pablo purchased adult and youth tickets for the football game. he bought x adult tickets for $74 each and y youth tickets for $35. write an expression that can be used to show the total cost, c, of all tickets.

c = (74 + 35)x
c = (74 + 35)(x + y)
c = 74y + 35x
c = 74x + 35y

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.

you,
