Answer:
B and D
Step-by-step explanation:
When y varies inversely as x ⇒ y*x=k
y=27 and x=40 ⇒27*40=1080=k
y*10=1080
y=1080:10
y=108
Only the first one works
y = 3(-1)-2 = -5
y = -(0) -6 = -6 not -2
This is a substitution problem...

Answer:
x = 22, y = 22/7
Step-by-step explanation:
solve for y using first equation:
-2 + 3y = 20
3y = 22
y = 22/7
substitute 22/7 into second equation:
7y = x
7(22/7) = x
x = 22
