Answer:
so 2a+3b=±13
Step-by-step explanation:
4a²+9b²=97
ab=6
2a+3b=?
by using formula
(a+b)²=a²+b²+2ab
(2a+3b)²=(2a)²+(3b)²+2(2a)(3b)
(2a+3b)²=4a²+9b²+12ab
putting values
(2a+3b)²=97+12(6)
(2a+3b)²=97+72
(2a+3b)²=169
taking square root on both sides
√(2a+3b)²=√169
2a+3b=±13

Answer:
Here we will find the pressure exerted by the gas?
Kinetic theory of gases shows the relationship between the Pressure of an ideal gas with the speed of molecules, or their average translational kinetic Energy
P
=0.667N/Vvr
where
P =Gas pressure?
vr = average translational kinetic energy of each atom =2.70×10⁻²³ J
N/V = number of gas atoms per volume = 6.76×10²⁰ atoms/cm³ = 6.76×10²⁶atoms/m³
P = 0.6667 x 6.76×10²⁶ x 2.70×10⁻²³ = 0.01217Pa

So, if y = 1, then all you have to do is plug in 1 for y in the first equation! :)
2x + 4y = 10
2x + 4(1) = 10
Simplify.
2x + 4 = 10
Subtract 4 from both sides.
2x = 6
Divide both sides by 2.
x = 3
So, your answer is a) x = 3, y = 1
