PLEASE PLEASE PLEASE HELP FAST WILL REPORT ANY TROLLS ABC is an isosceles right triangle in which AB has a slope of -1 and mABC = 90°. ABC is dilated by a scale factor of 1.8 with the origin as the center of dilation, resulting in the image A'B'C'. What is the slope of B'C'?

A. - 1

B. 0

C. 1

D. 1.5

E. 2

Step-by-step explanation:

Given

This means that AB⊥BC

The dilation doesn't affect the shape of the triangle, therefore:

Perpendicular lines have negative reciprocal slopes. In other words the product of the slopes is  - 1.

Let the slope of B'C' is x, then:

Correct option is C

so, converting firstly the mixed fractions to improper fractions and then "adding".

$5.41

step-by-step explanation:

$20 - $14.51 = $5.49.
