Step-by-step explanation:
Answer:
1.5 hours to 525 km
Speed in km/h=
Step-by-step explanation:
XD
solution is (4, - 7 )
given the equations
y = 2x - 15 → (1)
4x + 3y = - 5 → (2)
substitute y = 2x - 15 into (2)
4x + 3(2x - 15) = - 5
4x + 6x - 45 = - 5
10x - 45 = - 5 ( add 45 to both sides )
10x = 40 ( divide both sides by 10 )
x = 4
substitute x = 4 into (1) for corresponding value of y
y = (2 × 4 ) - 15 = 8 - 15 = - 7
solution is (4, - 7 )
We first assume that this gas is an ideal gas and we use the ideal gas equation to determine the answer. It is expressed as:
PV = nRT
Molar volume can be obtained from the equation by V/n.
V/n = RT/P
Therefore, the correct answer from the choices listed above is option A, <span>at 273 K and at 2.0 atm.</span>
Both these expression are written in slope-intercept form. y = mx + b
m = slope
b = y-intercept
We can find the slope of each expression by finding what m is in each equation.
y = -3x + 2 -> m = -3
y = 4x - 5 -> m = 4
Remember that m = slope
