PLEASE HELP!!!!<br> i need help on all of these but if you only have 1 answer that’s still great
hodyreva [135]

Answer:

n = -6

x = -7

n = 27

Step-by-step explanation:

Question 1

-3n - n + 12 = 36

First we get all the variables to one side using subtraction property of equality.

-3n - n + 12 (-12) = 36 (-12)

-4n = 24

divide by the coefficient of n to isolate the variable

-4n/-4 = 24/-4

n = -6

Question 2

-2x - 3x - 15 = 20

-5x - 15 = 20

-5x = 35

x = -7

Question 3

3 + n/9 = 6

Isolate the n variable

n/9 = 6 - 3

multiply by 9

n = 27

Which system of equations can be used to find the roots of the equation 4x2 =x3 +2x?
ra1l [238]

Answer:


<h2>\left \{ {{y=4x^2} \atop \\ \\ {y=x^3+2x}} \right.</h2>

Explanation:


An equality can be transformed in a system of equations by making each side equal to a new variable. In this case the variable y was made equal to each side.


See that may find the solution of such system by graphing both functions in a same coordinate system, where the intersection of the functions would show the solution of the system.


I show you that in the attached image. In such graph, the red curve is the function y = x² and the blue function is y = x³ + 2x.


The intersection point is (0,0) meaning that the solution is x = 0, y = 0.
