Answer: V (4,-2)

Step-by-step explanation: The coordinate x from the vertex is

x = -(-8)/2 = 4. Replacing the value of x, we write: y = 4^2 - 8.4 +14;

y = 16 - 32 + 14 ; y = -2.

Therefore, V (4,-2).

Answer:

-2

Step-by-step explanation:

Get the equation in the form y = ax2 + bx + c.
Calculate -b / 2a. This is the x-coordinate of the vertex.
To find the y-coordinate of the vertex, simply plug the value of -b / 2a into the equation for x and solve for y.

Which expressions are equivalent to z + (z + 6) z+(z+6)z, plus, left parenthesis, z, plus, 6, right parenthesis ?

Scorpion4ik [409]

In the question, the given expression is

$z+(z+6)$

And we have to find the equivalent expression to the given expression .

First we remove the parenthesis

$z+z+6$

Now we combine the like terms, and here like terms are z and z, therefore on combining , we will get

$z+z+6 = 2z+6$

And that's the required equivalent expression .
