Answer:

Step-by-step explanation:

The y axis is the vertical axis; the one going up and down.

A reflection means that a point is an equal distance away from its reflector as the basis was.

A was a reflection across the line y=x.

B was a reflection across the x axis with a 90 degree rotation.

C was a reflection across the x axis.

That leaves D.

Answer:

$\frac{x - 4}{x - 3}$

Step-by-step explanation:

$\frac{ {x}^{2} - 8x + 16 }{ {x}^{2} - 7x + 12}$

Lets split the numerator and denominator.

$= > \frac{ {x}^{2} - 4x - 4x + 16}{ {x}^{2} - 3x - 4x + 12}$

Lets factorise the numerator and denominator.

$= > \frac{x(x - 4) - 4(x - 4)}{x(x - 3) - 4(x - 3)}$

$= > \frac{(x - 4)(x - 4)}{(x - 3)(x - 4)}$

Cancelling x - 4 from numerator and denominator ,

$= > \frac{x - 4}{x - 3}$

Quadratic equation has 5x+0 as a linear factor what value is a zero of the associated quadratic function.

natka813 [3]

Answer:

x = 0

Step-by-step explanation:

The zero is the value of x that makes the linear factor zero:

5x +0 = 0

5x = 0 . . . . . simplify

x = 0/5 = 0 . . . . divide by 5

The associated zero is x = 0.
