A set of weights includes a 4lb barbell and 6 pairs of weight plates. Each pair of plates weighs 20lbs. If x pairs of plates are added to the barbell, the total
weight of the barbell and plates in pounds can be represent by
f (x) = 20x + 4.
What is the domain of the function for this situation?

i wish i could you, i have no idea how to answer this

step-by-step explanation:

c. 1,233 miles

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
