Asystem of equations is given below. y = 2x + 1/4 and 2x - 1/4

which of the following statements best describes the two lines?

they have the same slope but different y-intercepts, so they have no solution.
they have the same slope but different y-intercepts, so they have one solution. they have different slopes but the same y-intercept, so they have no solution.
they have different slopes but the same y-intercept, so they have one solution.

Ahigh-altitude spherical weather balloon expands as it rises, due to the drop in atmospheric pressure. suppose that the radius r increases at the rate of 0.02 inches per second, and that r = 36 inches at time t = 0. determine the equation that models the volume v of the balloon at time t, and find the volume when t = 360 seconds. v(t) = 4π(0.02t)2; 651.44 in3 v(t) = 4π(36 + 0.02t)2; 1,694,397.14 in3 v(t) = four pi times the product of zero point zero two and t to the third power divided by three.; 4,690.37 in3 v(t) = four pi times the quantity of thirty six plus zero point zero two t to the third power divided by three.; 337,706.83 in3
