Answer:

(0, 1)

(4, 17)

Step-by-step explanation:

2x^2 - 4x + 1 = 4x + 1

2x^2 - 8x = 0

x(2x - 8) = 0

therefore either

x = 0

or

2x - 8 = 0

2x = 8

 x = 4

(0, 1)

(4, 17)

I have a really bad grade in Geometry right now and I
Andrews [41]

Answer:  A. (x - 4, y - 2)

               B. (x + 7, y - 11)

<u>Step-by-step explanation:</u>

A) How do you get the x-coordinate of 3 to become a x-coordinate of -1?      by subtracting 4    -->    x - 4

   How do you get the y-coordinate of 5 to become a y-coordinate of 3?      by subtracting 2    -->    y - 2

The transformation is: (x - 4, y - 2)

B)  How do you get the x-coordinate of -4 to become an x-coordinate of 3?     by adding 7    -->    x + 7

    How do you get the y-coordinate of 11 to become a y-coordinate of 0?     by subtracting 11    -->    y - 11

The transformation is: (x + 7, y - 11)

Suppose that $x,y,z$ are positive integers satisfying $x \le y \le z$, and such that the product of all three numbers is twice t
valina [46]

The possible values of z is an illustration of the sum operator

The sum of all possible values of z is 17

<h3>How to determine the possible sum of z?</h3>

The conditions in the question are:

x <= y <= z

xyz = 2(x + y + z)

Using the trial by error method, the possible values of x, y and z are:

  1. x = 1 , y = 3 , z = 8
  2. x = 1 , y = 4 , z = 5
  3. x = 2 , y = 2 , z = 4

The sum of the z values are:

z = 8 + 5 + 4

Evaluate the sum

z = 17

Hence, the sum of all possible values of z is 17
