Pre-calc, need some help. Which parametric equations represent y = – |x|? Check all that apply.
x = –t and y = |–t|
x = t2 and y = –|t2|
x = 2t and y = –|2t|
x = t3 and y = |t3|
x = t + 4 and y = –|t + 4|

C and E

Step-by-step explanation:

x= 2t and y= -|2t| / x= t + 4 and y= -|t + 4|. I got in right on edg

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

how to award brainliest:

you must wait until 2 people answer to award brainliest. i'm pretty sure that it should be next to the "" and "comments" buttons.
