The graph below shows four straight lines, W, X, Y, and Z: Graph of line W going through ordered pairs negative 4, negative 2, and negative 1, 5. Graph of line X going through ordered pairs negative 2, negative 1, and 0, 5. Graph of line Y going through ordered pairs negative 1, negative 3, and 1, 3. Graph of line Z going through ordered pairs 0, negative 5 and 2, 1. Which line is represented by the function f(x) = 3x + 5? (1 point) Line W Line X Line Y Line Z

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.

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.

27 +27 or 27times 2=54

the diffrence is 0
