Subtracting 3xy2 from 8xy2 gives the same result as the expression as
a) 3xy2-8xy2

b)-7xy^2-2xy^2

c)7xy^2-2xy^2

answer: can you give the

step-by-step explanation:

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
