2(11 + 4n) - 2(6n + 12) = -4n - 10

Solution or no solution?

{3 + i, 3 - i, 3, -1}

step-by-step explanation:

what is the original number? you forgot to add it.

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
