Ifa line segment has a length of 12 units and after a dilation the image

BlackZzzverrR [31]

<h3>Answer: Choice A) 1/3</h3>

================================================

Work Shown:

x = preimage length = 12

y = image length = 4

z = scale factor

z = y/x

z = 4/12

z = (1*4)/(3*4)

z = 1/3

The scale factor is 1/3.

This means the image is 1/3 of the length of the preimage.

if the lesser of two consecutive even integers is seven more than half the greater, what are the two integers?

beks73 [17]

Answer: 16 and 18

Step-by-step explanation:

Let the lesser of two consecutive even integers is x.

Hence, the bigger of two consecutive even integers is (x+2).

$\displaystyle\\x-\frac{x+2}{2}=7 \\$

Multiply both parts of the equation by 2:

$x(2)-(x+2)=7(2)\\2x-x-2=14\\x-2=14\\x-2+2=14+2\\x=16\\x+2=16+2\\x+2=18$
