Tell whether the graphs of the two equations are parallel
(24) y = 8x-3 , 8x + y =3
(25) 2x + y = 5 , -6 + 2x = y
(26) 2x + y = 5 , y = 0.5x - 3
(27) y = -0.6 + 2 , 5y + 3x = 8
(28) 8x + 3y = 9 , 3y - 4 = 8x
(29) 10x + 2y = 7 , 5x - y = 6

The table below shows the height of a ball  x  seconds after being kicked.  what values, rounded to the nearest whole number, complete the quadratic regression equation that models the data? f(x)  =  x2  +  x  +  0based on the regression equation and rounded to the nearest whole number, what is the estimated height after 0.25 seconds?   feet

which of the following sets of data would produce the largest value for an independent-measures t statistic? the two sample means are 10 and 20 with variances of 20 and 25 the two sample means are 10 and 20 with variances of 120 and 125 the two sample means are 10 and 12 with sample variances of 20 and 25 the two sample means are 10 and 12 with variances of 120 and 125

The roots of the function f(x) = x2 – 2x – 3 are shown. what is the missing number?
