To get the solution of the 2 equations, the graphs are plotted on a grid. Since we are told that, <span>4x^2-3x+6=2x^4-9x^3+2x, then solution set is found  where the two graphs intersect. 
Since we need both values of x and y, the solution set is represented by;
y coordinates of the intersection points and
x coordinates of the intersection points. </span>

Answer:

The x-coordinates of the intersection points.

Step-by-step explanation:

to solve this equation, we want to find the values of x that make the equation true.

Graphing the related system of equations, we find the point of intersection for the two.  This is the solution to the system of equations; the x-coordinate of this is the solution to the equation listed above.

Which of the following equations has the same solutions as the equation 3x + 2y = -12? Check all that apply.
Mariulka [41]

Answer:

B.\ -3x - 2y = 12

C.\ 15x + 10y = -60

E.\ 6x + 4y = -24

F.\ 1.5x + y =-6

Step-by-step explanation:

Given

3x + 2y = -12

Required

Determine equations with same solution as 3x + 2y = -12

For a solution to have the same solution as 3x + 2y = -12, the equation must be expressed as 3x + 2y = -12

A.\ 3x - 2y = 12

This can not be expressed as 3x + 2y = -12

B.\ -3x - 2y = 12

Multiply through by -1

-1(-3x - 2y) = 12 * -1

3x + 2y = -12

This has the same solution as the given equation

C.\ 15x + 10y = -60

Divide through by 5

\frac{15x}{5} + \frac{10y}{5} = \frac{-60}{5}

3x + 2y = -12

This has the same solution as the given equation

D.\ 6x + 2y = -12

Divide through by 2

\frac{6x}{2} + \frac{2y}{2} = \frac{-12}{2}

3x + y = -6

This can not be expressed as 3x + 2y = -12

E.\ 6x + 4y = -24

Divide through by 2

\frac{6x}{2} + \frac{4y}{2} = \frac{-24}{2}

3x + 2y = -12

This has the same solution as the given equation

F.\ 1.5x + y =-6

Multiply through by 2

2*1.5x + 2*y =-6*2

3x + 2y =-12

This has the same solution as the given equation

G.\ x + \frac{2}{3}y = -12

Multiply through by 3

3 * x + 3*\frac{2}{3}y = -12*3

3x + 2y = -36

This can not be expressed as 3x + 2y = -12

The equations with the same solution as 3x + 2y = -12 are the ones that we were able to expressed as 3x + 2y = -12.

And the equations are:

B.\ -3x - 2y = 12

C.\ 15x + 10y = -60

E.\ 6x + 4y = -24

F.\ 1.5x + y =-6

Sphinxa [80]

Answer:

280 miles

Step-by-step explanation:

So, 420 miles=12 gallons

That means that for 1 gallon you would be able to go 35 miles.

Just multiply that by 8. 35*8=280
