In the equation what is the value of x 1/4(x+4x) + 12= 1/2(2-x)+10

Step-by-step explanation:

1/4(x + 4x) + 12 = 1/2(2 - x) + 10

0.25(x + 4x) + 12 = 0.5(2 - x) + 10

0.25x + x + 12 = x - 0.5x + 10

1.25x + 12 = 0.5x + 10

1.25x + 12 - 12 = 0.5x + 10 - 12

1.25x = 0.5x - 2

1.25x - 0.5x = 0.5x - 0.5x - 2

0.75x = - 2

0.75x ÷ 0.75 = - 2 ÷ 0.75

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
