First, we need to isolate the variable x.
To isolate x, we simply need to multiply both sides by 9, which would result in x = 9
Answer:
x= -12
Step-by-step explanation:
Assuming this is a direct variation
y = kx
When y = -16 x =4 we can find k
-16 = k*4
Divide each side by 4
-16/4 = 4k/4
-4 =k
So
y = -4k
Y = 48
48 = -4x
Divide each side by -4
48/-4 = -4x/-4
-12 =x
Answer:

Answer:
43-5= 38 (subtract the y-intercept from the last number to see how many stamps were sold over the past two months)
38/2= 19 (the number of stamps sold over 2 months divided by how many months it took for those stamps to be sold)
19 is what goes in the box
