a. y= 12x3-5x
y=2x2+x+6
b. y=12x3-5x+6
y=2x2+x
c. y=12x3+2x2-4x
y=6
d. y=12x3+2x2-4x+6
y=0

Option (a) is correct.

The system of equation becomes

Step-by-step explanation:

Given : Equation  

We have to construct a  system of equations that  can be used to find the roots of the equation

Consider the given equation

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

becomes,

Thus, The system of equation becomes

Option (a) is correct.

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3
