The midpoint of AB is M(0,3). If the coordinates of A are (1, 2), what are the
coordinates of B?

  B = (-1, 4)

Step-by-step explanation:

M = (A+B)/2

2M -A = B . . . . solve for B

__

B = 2(0, 3) -(1, 2) = (2·0 -1, 2·3 -2)

B = (-1, 4)

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

homozygous. one is homozygous, while two is heterozygous.
