Factor the following expression using the gcf.

10dr - 60r

10r(d - 6)
5r(2d - 30)
r(10d - 60)
10r(d - 60r)

10r(d - 6).

Step-by-step explanation:

The GCF is 10r.

So the answer is:

10r(d - 6).

the one below it is a function

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
