which is the equation of the given line?

a: y = –2x
b : x = 4
c: y = x
d: y = 3

Still don't know what the given line is, so I'm just going to attach images of the graphs of each equation.

Graph 1: y = -2x

Graph 2: x = 4

Graph 3: y = x

Graph 4: y = 3

Hope this helps!

the answer is c

hope this !

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.
