Answer:
The answer is c
Step-by-step explanation:
5x+3y=19
multiply x 2: 10x+6y=38
2x-4y=-8
multiply by -5: -10x+20y=40
now you can add the two equations:
10x+6y=38
-10x+20y=40
add equations 0x+26y=78

Answer:
y
=
9 when x
=
4
Step-by-step explanation:
If y varies inversely as x then
XXX
x
⋅
y
=
c for some constant c
Given y
=
12 when x
=3 XXX
3
⋅
12
=c
XXX
⇒
c
=
36
So
XXX
x
⋅
y
=
36 and when
x
=
4
XXX
4
*y
=
36
XXX
⇒
y
=
9
