How do you factor out 4v(squared) - 16v + 7?

1 answer:

7 0

It is a square trinomial:
4v^2 - 16v + 7 = 0
lets multiply and divide all by 4, the square term coefficient:
(16v^2 - 16(4)v + 28)(1/4) = 0
(4v - 14)(4v - 2)(1/4) = 0
factor 1/4
(4v - 14)(4v - 2)(1/2)(1/2) = 0
and divide each:
(2v - 7)(2v - 1) = 0

Ava decided to move the cabinet to the

geniusboy [140]

Transformation involves moving a shape away from its original position

The transformation to move the cabinet to a new position is translation
The transformation to place the chair directly across the couch is reflection

The required diagrams to answer this question are missing; so, I will provide a general exam

(a) Moving the cabinets

The question says that the cabinets are moved away from their original position.

Since terms like "rotation" or "reflection" are not used, then the general transformation used for "moving" is translation.

Hence, the transformation is translation

(b) Changing the position of the chairs

The question says that the chairs would be placed directly across the couch.

The term "directly across" is used for reflection of a shape.

Hence, the transformation is reflection
