The reduced row echelon form of a system of linear equations is given. Write the system of equations corresponding to the given
morpeh [17]

Answer:

  a. x +8z = -1

  b. y +5z = 2

  c. 0 = 0

  d. (x, y, z) = (-1-8z, 2-5z, z)

Step-by-step explanation:

As with the original matrix, the first three columns are the coefficients of the respective variables, and the last column is the constant on the right of the equal sign.

a. The first row represents the equation ...

  x + 8z = -1

__

b. The second row represents the equation ...

  y + 5z = 2

__

c. The third row represents the equation ...

  0 = 0

This equation expresses a truth, so indicates the original system of equations was consistent, but dependent. (a third row of 0 0 0 1 would indicate inconsistent, no solution)

__

d. The system is consistent but dependent. The solution can be written as ...

  (x, y, z) = (-1-8z, 2-5z, z) . . . . where z is a free variable

Y = x² - 4x convert from standard to vertex form​
Pepsi [2]

Answer:

y = (x-2)^{2} -4

Step-by-step explanation:

To complete the square: add 4 to both sides because the product of 4 as 2 as the factor which 2 * 2 so 2^{2}

y +  ? = x^{2} - 4x + ?

y +  2^{2} = x^{2} - 4x + 2^{2}

y + 4 = x^{2} - 4x + 4

Now we can factor the expression

y + 4 = (x-2)^{2}

Move the 4 to the other side to isolate y which changes the sign

y = (x-2)^{2} - 4
