An image Point has coordinates B'( 7, -4 ). Find the coordinates of its preimage if the translation used was (x + 4, y + 5 ).
B(11,1)
B(3,1)
B(3,-9)
B(11,-9)
Pls help.thx y'all

Given that the image point has coordinates B'(7,-4).

The coordinates of its preimage if the translation used was

We need to determine the coordinates of the preimage.

The coordinates of the preimage:

The coordinates of the preimage of the point B' can be determined by substituting the points of B' in the translation.

Thus, we get;

Substituting the coordinates, we have;

Simplifying, we get;

Therefore, the coordinates of the preimage is B(11,1)

Hence, Option A is the correct answer.

unless you made a typo, the answers are both a and c.

step-by-step explanation:

1.5/3 is .5 whereas 3/9 is .3333333 not proportional

22/33 is .66666 and 4/6 is also .66666 proportional

2/4 is .5 whereas 142/213 is .66666 not proportional

14/7 is 2 and 7/3.5 is also 2 proportional

you could've also checked it by doing this simple division:

if the larger fraction divides with the smaller fraction to equal 1, it is proportional. so let me show you what i mean:

when i divide 22/33 by 4/6 i get 1, so we know it is proportional, and it is the same with 14/7 and 7/3.5. now if i divide 3/9 by 1.5/3 i get .66666 so therefore we know it is not proportional.

there are many ways to do this so i wanted to show you some possible ways.
