Ryne is asked to graph this system of equations: 6x - 4y = 2
-2y+ 3x = 1
How many times will the lines intersect?
A. There is no way to tell without graphing the lines first.
B. The lines will intersect infinitely many times, because they are
identical.
O
C. The lines will not intersect, because this system has no solutions.
O
D. The lines will intersect once, because this system has one
solution.

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.

the answer is b
