Answer:
Step-by-step explanation:
y*1/x
y=k/x where k is the constant of variation
when y=7, x=-4
7=k/-4
k=-28
when x=5
y=-28/5
note: * is used as symbol of variation
1,5,7,35.... hope i helped!
-4x-2(8x=1)=-(2x-10)
-First, use the distributive property.
So distribute -2 to 8x=1 then distribute the negative - to (2x-10)
So it'd be: -4x-16x=-2=-2x+10
Then combine like terms:
-20x=-2=-2x+10
-18x=-2=10
-18x=8
Divide -18x by 8
x=-2.25
Yes because 27 divide by 9 is 3 and if you times 9 and 3 you will get 27
