Solve x2 + 6x = 7 by completing the square. Which is the solution set of the equation?
{-7, 13}
1-3 - 710, -3 + 710)
13 - V10, 3 + V10
{1, 7}

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

8(1/6)

step-by-step explain:

49/6= 48

8 (1/6)

the value of x is 28.2
