Answer:

B: One solution

Step-by-step explanation:

The graphs show that the two lines intersect at one point. This point represents the ONE solution of this system of equations.

If the lines did not intersect, the system would have no solution.

If the lines coincide, the system would have infinitely many solutions.

The volume of a gas in cubic centimeters v,varies inversely with the pressure of the gas in liters per square centimeters,p when

scoundrel [369]

Answer:

The volume of the gas is $145.45\ cm^{3}$

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form $y*x=k$ or $y=k/x$

Let

v------> the volume of a gas in cubic centimeters

p-----> the pressure of the gas in liters per square centimeters

$p*v=k$

we have

$v=16\ cm^{3}, p=20\ l/cm^{2}$

substitute and solve for k

$k=16*20=320$

The equation is $p*v=320$

<em>Find the volume of the gas when the pressure is 2.2 L/cm2</em>

For $p=2.2\ l/cm^{2}$ Find the value of v

substitute in the equation

$(2.2)*v=320$

$v=320/2.2=145.45\ cm^{3}$
