what is the midpoint of the line segment with endpoints (-4 -3) and (-7 5) A. (1.5, -4) B. (-4,1.5) C. (1, -3.5) D. (-3.5, 1)

given,

the points are(-4,-3) and (-7,5)

now, midpoint=

or, midpoint =

therefore the midpoint is (-11/2,1)... ans

hope it helps..

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.
