In the ordered pair ( 4,-6) ,which is are correct? a.-6 is the abscissa.
b. it corresponds to a point on the cartesian plane.
c. ordered pair (4,-6) is same as (-6,4).
d. both a and c.

In the ordered pair ( 4,-6) :

2 over 5

step-by-step explanation:

the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
