The graph shows the relationship between mass and volume for pure silver. Use the graph to determine the density of pure silver

Natalija [7]

Answer:

C. Slope and $10.49 g/cm^3$

Step-by-step explanation:

We're missing the graph itself, but I can make an educated guess:

- Assuming x = volume and y = mass:

$p = \frac{m}{v}$

density = mass/volume

x = volume = run

y = mass = rise

mass/volume = rise/run = slope

The slope of the line (assuming the graph is purely linear) represents mass/volume, which is the formula for density.

I had to Google the density of silver itself. Do the math from the graph for a more appropriate answer, as the graph may be less scientifically precise.

Solve the equation 3x-2y =7, x+2y= -3

swat32

Answer:

x=1
y= -2

Step-by-step explanation:

3x-2y =7
x+2y= -3
4x=4
x=4/4
x=1
3x-2y=7
3(1)-2y=7
3-2y=7
-2y=7-3
-2y=4
2y=-4
y=-4/2
y= -2
Verify solution
x+2y= -3
1+2y= -3
2y=-3-1
2y= -4
y= -4/2
y= -2
