Question:5x^-2y^10 over 2x^-1(-3x^-3y^-1)^-2

Answers:(45/2)x^-7 y^8

Question:

Answers:

Question:y = x^2 + x + 11 The value of y is a prime number when x = 0 , 1 , 2 , 3 The following statement is NOT true.. 'y= x^2 + x + 11 is ALWAYS a prime number when x is an interger' show that the statement is not true! PLEASE HELP NEEDED

Answers:All you need is a counter example. For example, try x = 10. y = 10 + 10 + 11 y = 121 121 is 11 which is not prime.

Question:f(x) = 2x2 + 3x 2. (a) Solve the equation f(x) = 0. (b) Sketch the curve with equation y = f(x), showing the coordinates of any points of intersection with the coordinate axes. (c) Find the coordinates of the points where the curve with equation y = f( 1/2 x) crosses the coordinate axes. (3) When the graph of y = f(x) is translated by 1 unit in the positive x-direction it maps onto the graph with equation y = ax^2 + bx + c, where a, b and c are constants. (d) Find the values of a, b and c.

Answers:a (2x-1)(x+2) x = -2 or 1/2

Fallout New Vegas- "Very Hard" Character Build :This is a character build designed to conquer even the most difficult battles on Very Hard difficulty in Fallout New Vegas, without depending on gimmick weapons like the Alien Blaster.

This also makes the cowboy repeater much more powerful, which is useful until you get the Sniper Rifle. -I recommend using Psycho/Med-X liberally, the power bonus is very noticeable and I always use it before difficult fights (such as against deathclaws) -Confirmed Bachelor ...
