If the two lines a re parallel, they would have the same slop which means the red line would have a slope of - 2/3

The rigid transformations that maps ΔABC onto ΔFED by reflection then translation.

The correct option is (B).

<h3>What is Translation?</h3>

Translation is also another form of transformation whereby all the points of a figure are shifted at exactly the same distance and in the same direction without being resized, reflected nor rotated.

given:

ΔABC ≅ ΔFED are congruent by the SSS Congruence Theorem.

Hence, the rigid transformations that maps ΔABC onto ΔFED by reflection then translation.

Write in point-slope form an equation of the line through the pair of points. (3,12) and (5,9)

horrorfan [7]

Answer:

$\large\boxed{y=-\dfrac{3}{2}x+16\dfrac{1}{2}\to y=-1.5x+16.5}$

Step-by-step explanation:

The slope-intercept form of an equation of a line:

$y=mx+b$

m - slope

b - y-intercept

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points (3, 12) and (5, 9).

Substitute:

$m=\dfrac{9-12}{5-3}=\dfrac{-3}{2}=-\dfrac{3}{2}$

Put the value of a slope and coordinates of the point (3, 12) to the equation of a line:

$12=-\dfrac{3}{2}(3)+b$

$12=-\dfrac{9}{2}+b$

$12=-4\dfrac{1}{2}+b$ add $4\dfrac{1}{2}$ to both sides

$16\dfrac{1}{2}=b\to b=16\dfrac{1}{2}$

Finally:

$y=-\dfrac{3}{2}x+16\dfrac{1}{2}$

A small town had a population of 9,800 in 2005. Now, it is 6,300. Write an expression to find the percent of change. What is the

marshall27 [118]

Answer:

35.7% decrease

Step-by-step explanation:

Change in population:

9800 - 6300 = 3500 (decrease)

Percent change:

3500/9800*100% = 35.7% (rounded to the nearest tenth)
