Tomas is finding the coordinates of point a. he knows that point a has an x-coordinate of 8. he starts to compute the value of the y-coordinate. complete tomas’s work to answer the question. which is the coordinate of point a? (8, –6) (–6, 8) (6, –8) (–8, –6)

Answer with explanation:

Tomas is trying to find the coordinates of point A.

An ordered is written as , (x,y).

X coordinate of Point A = 8

Among the four given options,only option A has, x , coordinate =8

So, Coordinate of Point A = (8, -6).

Option A

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.

answer: the distance

step-by-step explanation:

to calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. to calculate the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) use the formula
