Step-by-step explanation:

whenever a complex number is a root of a polynomial with real coefficients, its complex conjugate is also a root of that polynomial. as an example, we'll find the roots of the polynomial..

x^5 - x^4 + x^3 - x^2 - 12x + 12.

the fifth-degree polynomial does indeed have five roots; three real, and two complex.

Verdich [7]

We have to get the y alone. So we'll subtract 3x on both sides.

Our new expression is y<-3x+8

Graph the equations to find the solution(s) to the system.

liraira [26]

By graphing both equations, we see that the solutions of the system of equations are (1.05, 4.05) and (-4.97, - 1.97)

<h3>How to solve the system of equations?</h3>

Here we have the system of equations:

y = x + 3

y = 13*(x + 5)*(x - 1).

To solve this system graphically, we need to graph both equations and see where the curves intercept.

The graph of the two equations can be seen below.

There are two solutions, one is (1.05, 4.05) and the other is (-4.97, - 1.97)

Answer: $x\leq 3$

PLEASE MARK ME BRAINLIEST

Step-by-step explanation:

1) Simplify both sides of the inequality:

$4x+8\geq 5x+5$

2) Subtract $5x$ from both sides:

$4x+8-5x\geq 5x+5-5x$

3) Simplify:

$-x+8\geq 5$

4) Subtract $8$ from both sides:

$-x+8-8\geq 5-8$

5) Simplify:

$-x\geq -3$

6) Divide both sides by $-1$ :

$\frac{-x}{-1} =\frac{-3}{-1}$

7) Simplify:

$x\leq -3$

By estimation, 3.9 turns into 4 and 5.3 turns into 5. The answer after estimation is 20 while the real answer is 20.67. Well u see by estimation we get an answer of two places right. So, real answer should also have two places.Place the decimal point after it.y43
