Triangle A'B'C' is formed using the translation (x + 2 y + 0) and the dilation by a scale factor of 1/2 from the origin. Which e

Scorpion4ik [409]

Answer:

$A"B" = \frac{AB}{2}$

Step-by-step explanation:

Given

$k = \frac{1}{2}$ --- scale factor

Required

Relationship between AB and A"B"

$k = \frac{1}{2}$ implies that the sides of A"B"C" are smaller than ABC

i.e.

$A"B" = k * AB$

$A"B" = \frac{1}{2} * AB$

This gives:

$A"B" = \frac{AB}{2}$

Complete the equation of the line through (3, -1) and (4, 7)

nikitadnepr [17]

Answer:

y = 8x -25

Step-by-step explanation:

The two-point form of the equation of a line can be used.

y = (y2 -y1)/(x2 -x1)(x -x1) +y1

y = (7-(-1))/(4-3)(x -3) +(-1)

y = 8(x -3) -1

y = 8x -25 . . . . slope-intercept form of the equation

_____

We don't know what you're starting with, so we don't know how to "complete the equation." Perhaps the above equation is sufficient for the task.
