Which system of equations can be used to find the roots of the equation 12 x 3-5x=2 x 2+x+6

kirill [66]

Answer:

Option (a) is correct.

The system of equation becomes

$y=12x^3-5x\\\\ y=2x^2+x+6$

Step-by-step explanation:

Given : Equation $12x^3-5x=2x^2+x+6$

We have to construct a system of equations that can be used to find the roots of the equation $12x^3-5x=2x^2+x+6$

Consider the given equation $12x^3-5x=2x^2+x+6$

To construct a system of equation put both sides of the given equation equal to a same variable.

Let the variable be "y", Then the equation $12x^3-5x=2x^2+x+6$

becomes,

$12x^3-5x=y=2x^2+x+6$

Thus, The system of equation becomes

$y=12x^3-5x\\\\ y=2x^2+x+6$

Option (a) is correct.

Monica [59]

Answer:

First of all you spelled years instead of yards. But I'd say that Mallory has the longer piece of wire.

Step-by-step explanation:

Because of 2.16 yds over 1 times 1 meter over 3 yds. You divide them instead of multiplying, you get 1.97 meters.

Question 2 of 5

jeka57 [31]

The number of solutions in each equation are as follows:

1 solution: 4^x = 2^{-x}
2 solution: 3/2x + 2 = 2^{x} + 1 and 3x + 1 = 2^{-x}.
No solution: 4^x + 2 = 3^x - 1 and 2x - 5 = 3^{x} + 2.

<h3>How to determine the number of solutions?</h3>

In order to determine the number of solutions, we would split the single equation to two different equations and then plot a graph, so as to reveal their solutions.

This ultimately implies that, the number of solutions is equal to the point of intersection between the lines of the equations plotted on a graph.

In conclusion, the number of solutions in each equation are as follows:

1 solution: 4^x = 2^{-x}
2 solution: 3/2x + 2 = 2^{x} + 1 and 3x + 1 = 2^{-x}.
No solution: 4^x + 2 = 3^x - 1 and 2x - 5 = 3^{x} + 2.
