Factor out the greatest common factor. If the greatest common factor is 1, just retype the polynomial. 40d10–43d8+26d7–15

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

answer: 12x^2+6x

step-by-step explanation:

6x does not equal 24x. hope it works!

i think the answer is b x = 1, y = 35/2
