Write a translation rule that maps point D ( 7 , − 3 ) onto point D ' ( 2 , 5 ). I NEED HELPPPP!

anzhelika [568]

Answer:

$T_{ - 5 ,8} \: or \: D'(x,y) →D(x - 5,y + 8)$

Step-by-step explanation:

$T _ { ? ,?}$

$D'(x,y) →D(x \pm ?,y \pm ?)$

given D : (7,-3), and D' : (2,5)

the coordinates of D can be represented as (x1,y1), and the coordinates of D' can be represented as (x,y).

you can simply take the difference in the x values and difference in the y values from the preimage to image.

like this:

f'(x,y) → f(x+(x-x1),y+(y-y1)) : $T _ {(x-x_1),(y-y_1)}$

D'(x,y) → D(x+(2-7),y+(5--3))

D'(x,y) → D(x-5,y+8) : $T _ {-5 ,8}$

A contest on a game show receives -25 points for each wrong answer what integer represents the change in periods after three wro

Paladinen [302]

To represent the change in points, you can think of it in two ways:

1. You will go down 25 points for every wrong answer, so -25 + -25 + -25 would represent what is happening. They are all negative, so you keeping moving down in value.

2. You can also think of this as 3 groups of -25.

Both answers are -75. The answer is negative because the change was down in points.

-75 is the integer that represents this situation.
