mars1129 [50]3 years ago
5 0

Answer:

No complex roots; 3 real roots

Step-by-step explanation:

If a third order polynomial has any complex roots, then as a rule it has 1 real root and 2 complex roots.  In this particular case, the polynomial has three real roots, as can be determined by graphing the function.  The graph crosses the x-axis in 3 places.

What is the solution to the system of equations? "-6x2/5y=8" 1/2x+3y=29
prohojiy [21]

The answer choice which represents a solution to the system of equations is; (–2, 10).

<h3>Which answer choice is a solution to the systems of equations?</h3>

The system of equations as given in the task content is;

-6x - (2/5)y = 8

(1/2)x +3y = 29

Hence, by making x subject in equation 1 and substitution; we have;

x = (-0.4y -8)/6

Hence; (0.4y -8)/12 + 3y = 29.

(0.4y -8) + 36y = 348

35.6y = 356

y = 10

and x = (-0.4(10) -8)/6 = -2.

I DON’T GET THIS ONLY NEED NUMBER 6 PLEASEEE!!!!!
Sophie [7]

\huge\text{Hey there!}

\huge\text{The word \bf{product}}\huge\text{ means multiply in}\\\huge\text{mathematics.}

\huge\text{The number is unknown so we can label}\\\huge\text{it as: x}

\huge\text{Your equation will be setup like this: -2.5x = 60}

\text{-2.5x = 60}\\\text{First divide both sides by -2.5}\rightarrow\dfrac{-2.5\text{x}}{-2.5} = \dfrac{60}{-2.5}\\\text{Cancel out:}\dfrac{2.5\text{x}}{2.5}\text{ because it equals 1}\\\\\text{Keep:}\dfrac{60}{-2.5}\text{because it helps us find the unknown number}\\\\\\\boxed{\boxed{\text{Answer: x = -24}}}\checkmark

\text{Good luck on your assignment and enjoy your day!}
