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.

Doss [256]

Answer:

3.83

Step-by-step explanation:

Mean of x = Σx / n

Mean of x = (14 + 19 + 13 + 6 + 9) / 5 = 12.2

Sum of square (SS) :

(14-12.2)^2 + (19-12.2)^2 + (13-12.2)^2 + (6-12.2)^2 + (9-12.2)^2 = 98.8

Mean of y = Σy / n

Mean of y = (101 + 89 + 48 + 21 + 47) / 5 = 61.2

Σ(y - ybar)² = (101-61.2)^2 + (89-61.2)^2 + (48-61.2)^2 + (21-61.2)^2 + (47-61.2)^2 = 4348.8

df = n - 2 = 5 - 2 = 3

Σ(y - ybar)² / df = 4348.8 / 3 = 1449.6

√(Σ(y - ybar)² / df) = √1449.6 = 38.074

Standard Error = √(Σ(y - ybar)² / df) / √SS

Standard Error = 38.074 / √98.8

Standard Error = 3.83

What is the value of x? <br><br> 3x+17=14x-5
Feliz [49]

Answer:

x=2

Step-by-step explanation:

3x+17=14x-5 so...

22=11x (subtract 3x and add 5 to both sides)

2=x (divide both sides by 11)
