Ab contains the points a(–3, 3) and b(1, 4). yz contains the points y(–4, 7) and z(–2, y). ab and yz are perpendicular. find the value of the y-coordinate of point z.
a.
y = –1
b.
y = 1
c.
y = 8
d.
y = 15

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.

alright well the answers to your question is
