Answer 4

is this the answer?

Part A:
1) reflection with respect to the horizontal axis whose equation is y=−1
2) horizontal translation to the right by 7 units;
3) vertical translation upward by 2 units"
in order to write the coordinates of the vertices A,B,C,D you have to make such three transformation on a cartesian plane, so you can see exactly the values of such coordinate
Part B:
reflections and translations are special isometries, so they don't change the shape and the size of the quadrilateral ABCD, then the geometrical shape obtained, is congruent with the starting geometrical shape

Answer 5

??

Answer 6

@volleyballlover55
The second part of the answer is very well done, congrats.
In the first part, you seem to have to make up your mind about about which line to reflect (first step). You said "the horizontal axis whose equation is y=−1".
An axis is a reference point, so the horizontal axis is y=0 (x-axis). I think you do want to reflect about the \(line\) y=-1.
Apart from that, the answer is perfectly correct, even though it could have been done in just two steps if you reflect it about a different line (the x-axis).

Answer 7

@mathmate ok so what can i say for part A? @mathmate

Answer 8

You don't have to change anything, your answer is perfectly correct.

Answer 9

i thought you said my first step was wrong.... how can i re-write the first step?

Answer 10

Perhaps just change the word "horizontal axis" to "horizontal line" to avoid confusion.

Answer 11

It's not wrong, just confusing to say "the horizontal axis with an equation of y=-1". The part y=-1 would govern anyway.

Answer 12

ok so is this correct now?

reflection with respect to the horizontal line (axis) whose equation is y=−1

Answer 13

@mathmate

Answer 14

It's ok.

Answer 15

will i get it right?

Answer 16

in part A... is step 3 correct?

Answer 17

Yep, if you reflect about y=-1, step 3 is correct.

Answer 18

do i have to say that? or do i leave it how is it?

Answer 19

smartnerd said that this was the answer for part A is x+65=120
x=120-65=55 degrees

Answer 20

Your answer for both parts are good, as they are (were).
I am not catching what x+65=120 is referring to.
Will catch you later.
