Can someone tell me which expression is equivalent ?

D. 12h + 6k

Step-by-step explanation:

in order to find the equivalent expression, you have to simplify it (at least in this case)

when simplifying the expression, you use the distributive property (multiplying 3 to both 4h AND 2k). 3(4h) = 12h, and 3(2k) = 6k, so it is 12h + 6k

c

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
