A system of equations is created by using the line represented by2x+4y=0And the line represented by the data in the table below What is the X value of the solution to the system if x -1 and y is 8

x = 2

Step-by-step explanation:

From the data, we obtain the slope :

-1, 8 ; 3, - 4

Slope = Rise / run

Rise = y2 - y1 = (-4 - 8) = - 12

Run = x2 - x1 = (3 - (-1)) = 4

Slope, m = - 12 / 4 = - 3

Recall:

Equation of line :

y - y1 = m(x - x1)

y - 8 = - 3(x + 1)

y - 8 = - 3x - 3

y = - 3x - 3 + 8

y = - 3x + 5

Substituting y = - 3x + 5 into the equation 2x+4y= 0

2x + 4(-3x + 5) = 0

2x - 12x + 20 = 0

-10x = - 20

x = 2

6 meters

step-by-step explanation:

it is g.

step-by-step explanation:

ad does increase as the sales increases so g. is right.

j. it really kick itself off because it says " always " .

h. nothing remains that same, everything changed through out the graph!

f. it would be right if it says " ad decrease = sales decrease" so right off the bat, that's wrong.
