Answer:-3
Step-by-step explanation:
A:93
B: slope
the slope is the rate of change of the line.
this line models the distance between cop and the driver. note that the
cop is standing still while the sports car is moving away at 93 mph
if
the x-axis is in hours and the y-axis is in miles, then slope =
rise/run = km/h, which is kilometers per hour. the slope is the rate of
change of distance for the distance vs time graph
therefore the slope is 93 mph
Hey There,
The equation would be y = 4x - 45
Point slope formula
(y-y1)=m(x-x1)
Plug in the numbers
(y-3)=4(x-12)
Solve for y.
4 * x = 4x
4 * -12 = -48
Bring 3 to the other side (change the sign)
-48 +3 = 45
Therefore, the equation would be y = 4x - 45
I believe that choice A is the best answer out of those given above.

The answer would be: 0.5L
This question can be solved using the ideal gas formula PV=nRT where
P= pressure
V= volume
n= number of molecule
R= constant
T= temperature
In this question, the temperature and number of the particle are not changed. The pressure is changed to twice amount. Since the pressure is inversely related to the volume, the volume should become half of the original.
PV=nRT
V=nRT/P
V1/V2= (nRT/P1)/(nRT/P2)
V1/V2= (1/270)/(1/540)
V1/V2= (1/1)/(1/2)
V1/V2 = 2
V1= 2V2
1L= 2V2
V2= 1/2 L
