Step-by-step explanation:

A. 5x=12x-14

you will simplify the equation to the form, which is simple to understand

5x=12x-14

We move all terms containing x to the left and all other terms to the right.

+5x-12x=-14

We simplify left and right side of the equation.

-7x=-14

We divide both sides of the equation by -7 to get x.

x=2

B. 5B+12=BB=28

you will move all terms to the left:

.5B+12-(BB)=0

you will move all terms containing B to the left, all other terms to the right

.5B-BB=-12

Which of the following points is a vertex for the image produced by a dilation about the origin with a scale factor of 1/2?

MA_775_DIABLO [31]

Answer:

A (0,3)

Step-by-step explanation:

The given trapezoid has vertices:

(0,6), (7,12), (7,9) and (0,12).

We want to choose from the given options, a point that is a vertex for the image produced by a dilation about the origin with a scale factor of 1/2.

Note that the mapping for such a dilation is:

$(x,y)\to( \frac{1}{2} x, \frac{1}{2} y)$

This implies that:

$(0,6)\to(0,3)$

$(7,12)\to(3.5,6)$

$(7,9)\to(3.5,4.5)$

$(0,12)\to(0,6)$

Therefore correct choice is (0,3)
