What is the ordered pair of X′ after point X (3, 4) is rotated 180°?  X′ (3, −4)  X′ (−3, −4)  X′ (−4, 3)  X′ (−4, −3)

The figure shown has two parallel lines cut by a transversal:Which angle is an alternate exterior angle to ∠7? ∠2  ∠1  ∠5  ∠8

A pair of parallel lines is cut by a transversal.If m∠A = (5x − 4)° and m∠B = (8x − 28)°, what is the value of x? 8  9.4  16.3  36

Two friends are sharing one half of a pizza that is divided into three pieces, as shown in the figure.If m∠AOB = (6x − 5)° and m∠BOD = (9x + 17)°, what is the value of x? 117.8  62.2  11.2  7.3

Factor the polynomial and use the factored form to find the zeros. (Enter your answers as a comma-separated list. Enter all answers using the appropriate multiplicities.)P(x) = x3 − x2 − 12x

Let y = 3 * sqrt( x )a) Find the change in y (delta y) when x = 4 and the change in x (delta x) = 0.2b) Find the differential 'dy' when x = 4 and 'dx' = 0.2

The original question was:32x-4(3x)+3=0I 'u' subbed for 3xand gotu2-4u+3 = 0(u-1)(u-3) = 0thereforeu = 1 or 3 (null factor theorem)therefore3x=1or3x=3I don't know what to do next though.
