we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y=kx
where
k is the constant of proportionality
Verify each table
table a
Let
x ----> distance
y ----> sound level
For each ordered pair calculate the value of k
k=y/x
so
(5,85) -----> k=85/5=17
(10,79) ----> k=79/10=7.9
the values of k are differents
that means
the table nor represent a proportional relationship
table b
let
x ----> volume
y ----> cost
k=y/x
(16,1.49) ----> k=1.49/16=0.093125
(20,1.59) ----> k=1.59/20=0.0795
the values of k are differents
that means
the table nor represent a proportional relationship

Planes intersect along a line.
Answer:
120:200
Step-by-step explanation:
3/8*320= 120
320-120=200
The LCD here is 12. Th,us, 1/6, 2/3 and 1/4 become:
2/12, 8/12 and 3/12.
Their sum is 13/12, or 1 1/12.

Slope could be found in the "m" variable of the equation: y = mx + b
You would see that 7 would be in the place of the variable "m"
Therefore, your slope, or rate of change, would be 7
Answer: 7
