Answer:

Equation has 1 real root and 2 complex roots.

Step-by-step explanation:

Given : x^{3} +x^{2} =  x -1.

To find : Which statement describes the roots of this equation.

Solution : We have x^{3} +x^{2} =  x -1.

We can write it as  x^{3} +x^{2} - x -1.

Graphs of both these functions shows one common point, this means that the equation x^{3} +x^{2} =  x -1 has one real solution (approximately, x≈-1.839).

But degree is 3 .

So, it has maximum 3 root.

Therefore, Equation has 1 real root and 2 complex roots.

Answer:

Equation has one real root and two complex roots.

Step-by-step explanation:

The equation x^3+x^2=x-1 consists of two parts. The left side of this equation can be represented by the function y=x^3+x^2 and the right side can be represented by the function y=x-1. Graphs of both these functions are shown in the attached diagram.

These graphs have one common point, this means that the equation x^3+x^2=x-1 has one real solution (approximately, x≈-1.839).

Given equation is cubic, then this equation has three roots. Since only one root is real, then two remaining roots are complex.

PLZZZZ HELP What is the slope of a line that is perpendicular to a line whose equation is 3y=−4x+2 ?
earnstyle [38]

\bf 3y=-4x+2\implies y=\cfrac{-4x+2}{3} \\\\\\ y=\stackrel{\stackrel{slope}{\downarrow }}{-\cfrac{4}{3}}x+\cfrac{2}{3}\impliedby \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}


so the slope of that line above is really -4/3, now


\bf \stackrel{\textit{perpendicular lines have \underline{negative reciprocal} slopes}} {\stackrel{slope}{-\cfrac{4}{3}}\qquad \qquad \qquad \stackrel{reciprocal}{-\cfrac{3}{4}}\qquad \stackrel{negative~reciprocal}{+\cfrac{3}{4}\implies \blacktriangleright \cfrac{3}{4} \blacktriangleleft}}
