In which quadrant is the abscissa negative and the ordinate negative? I II III IV

OpenStudy (anonymous):

what do you think it is?

OpenStudy (anonymous):

ik the answer xD

OpenStudy (anonymous):

i think its 3

OpenStudy (anonymous):

i hate that u juss cant give people answers

OpenStudy (anonymous):

yeah me too but dont give direct answers

OpenStudy (anonymous):

and yeah its 3

OpenStudy (anonymous):

yup wait isnt it 2?

OpenStudy (anonymous):

nope

OpenStudy (anonymous):

oh yeah your right lol didnt see it haha

OpenStudy (anonymous):

my guess was 3 but it turned out wrong :/

OpenStudy (anonymous):

magan you got the answer right you get a metal

OpenStudy (anonymous):

so its 2?

OpenStudy (anonymous):

no its 3

OpenStudy (anonymous):

i got confused

OpenStudy (anonymous):

wait well look at this

OpenStudy (anonymous):

i thought it was 2 but wasnt sure so i got this

OpenStudy (anonymous):

so 2 is right

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

would you mind helping with a few more?

OpenStudy (anonymous):

In which quadrant is the abscissa negative and the ordinate negative? It would be The answer is Quadrant II. Negative abscissa (negative x-axis) and positive ordinate (positive y-axis). The abscissa is a fancy term for "x-value" and the ordinate is a fancy term for "y-value."

Medal?

OpenStudy (anonymous):

@magan tag me if you need help

OpenStudy (anonymous):

what about this one? Determine the image of the point (1, 5) under a rotation of 180° about the origin. a.(1, 5) b.(-1, 5) c.(-5, 1) d.(-5, -1)

OpenStudy (anonymous):

Determine the image of the point (1, 5) under a rotation of 180 degrees about the origin. (1, 5) (-1, 5) (-5, 1) (-5, -1)

OpenStudy (anonymous):

The answer, (-5,1) since it is however 180 or under it would be a negative (5). I would love to explain it in a more clear way but I don't know how too explain this type of question for you.

OpenStudy (anonymous):

BRB

OpenStudy (anonymous):

Thanks alot :) i am also really stuck on this one A transformation T : (x, y) -> (x - 3, y + 1). Find the preimage of the point (4, 3) under the given transformation. a.(7, 2) b.(1, 2) c.(1, 4) d.(4/3, 3)

OpenStudy (anonymous):

its cool

OpenStudy (anonymous):

what grade are you in?

OpenStudy (anonymous):

the answer is 1,4

OpenStudy (anonymous):

@magan

OpenStudy (anonymous):

its fine im a freshman

OpenStudy (anonymous):

Ok im back, the answer would be.... Well first: a assume preimage would be the point it came from, so undo the transformation that was done... x+3 = 4 y+1 = 3 solve for x and y

OpenStudy (anonymous):

what did you get when you solved for x and y? what plus 3 equals 4? that "what" is then your x value same idea on the y part (so therefore) your answer would be C (1,4) just a little trick i do} @magan

OpenStudy (anonymous):

oh yeah my friend agrees with him its C

OpenStudy (anonymous):

what about this one? Which of the following describes the translation of the graph of y = x 2 to obtain the graph of y = -x 2 - 3? reflect over the x-axis and shift down 3 reflect over the x-axis and shift up 3 reflect over the y-axis and shift down 3

OpenStudy (anonymous):

Well, i hate to give out direct answers but reflect over the x-axis and shift down 3

OpenStudy (anonymous):

The answer would be b ithink

OpenStudy (anonymous):

@megan the answer is B

OpenStudy (anonymous):

Okay i got one last one Choose the kind or kinds of symmetry the following figure has: point, line, plane, or none. (Select all that apply.) The figure is 3 plane line point none

OpenStudy (anonymous):

point and lne

OpenStudy (anonymous):

my guess is line

OpenStudy (anonymous):

can you explain?

OpenStudy (anonymous):

me?

OpenStudy (anonymous):

yes
