The value of y = -32 , x = -8 .
<h3>What is the meaning of Direct Variation ?</h3>
Direct Variation is when a variable is dependent on the other variable such that , on increasing one variable the other also increases.
It is given that
x and y are two variables
and they are in direct variation
y ∝ x
y = k x
where , k is the proportionality constant
From the given data , y = 76 when x = 19
76 = k * 19
k = 4
The value of x , when y = -32
-32 = 4 * x
x = -8
Therefore for y = -32 , x = -8 .

Answer:
y = -6x - 6
Step-by-step explanation:
<u>First, subtract 12x from both sides:</u>
12x + 2y = -12
-12x -12x
-----------------------
2y = -12x - 12
<u>Divide both sides by 2:</u>
y = -6x - 6
Area of a circle is pi (r)^2
So area of semi circle is 1/2 pi (r)^2
Then area =32 pi or ~100.53
Steps on finding the volume of water :
1. volume . pour enough water from your cup into the graduated cylinder.
2. density . calculate the density by using the formula D=M/V . record the density in (g/m ) ^3 .
3. identify the samples . compare the values for density you calculated to the values in a chart.
