5. Assume each variable has a different value. Which relations below are functions?
a. {(a, b),(a, c),(a, d), (a, e) b. {(a, b), (b, b), (c, b), (d, b)}
c. {(a, b), (c, d), (e, f), (g, h) d. {(a, a), (b, c), (C, c), (d, e)}
A choices b and c only
B choices b, c, d only
C choice c only
OD choice a only

answer:

correct option is C I think so

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
