The image of the point (4,-2) under a rotation 180 degrees about the origin is A. (−2,−4) B. (−2,4) C. (−4,−2) D. (−4,2)

D

Step-by-step explanation:

(4,-2) is located in the fourth quadrant and to think about it, if you rotates it 90 degrees clockwise it will be located in the third quadrant and another 90 degrees it will be located in the second quadrant. And the the second quadrant is the opposite of the fourth quadrant so you will have to find the opposite of the numbers. The opposite of 4 is -4 and the opposite of -2 is 2 so you will have the new coordinates (-4,2)

rotating (4,-2) 180 degrees will be (-4,2)

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!

answer: answer is c!

ok i got to organize the

3/15 and 12/55

3*

aha

3*4 equals 12 but not

a: no

b:

8/24 12/35

no

gautie

it's c

5/18 = 25/90

5*5=25

18*5 = 90

hope that you!

one more happy customer!
