<h3>
Answer: 8</h3>
===========================================================
Explanation:
All direct variation equations are of the form y = kx, for some constant k.
We know that y = -8 and x = 4 pair up together. Let's use these two values to find k
y = kx
-8 = k*4
-8/4 = k
-2 = k
k = -2
Therefore, we go from y = kx to y = -2x
We can then find y when x = -4
y = -2x
y = -2*(-4)
y = 8
This is a word problem for 12.
Laura decided to throw a party. The DJ charged 2 dollars an hour and 4 dollars to use lights and fog. How long did the DJ play?
This one is for 11.
Kate wanted to go skating. When she got there it was 4 dollars an hour. The total cost was 12 dollars. How many hours did she skate?
2x=y where 2 is dollars per tomatoe, x is amount of pounds of tomatoes, and y is amount of money spent in total. say you got 3 pounds of tomatoes; the equation would be 2(3)=y. y=6. Hope I helped!
