ok so i need you to tell me how many solutions does this problem have but if none then say no solution but 3(x + 4) = 3x + 4

-8

Step-by-step explanation:

3( x + 4 ) = 3 x + 4 = 3 x + 4

3 x + 12 = 3 x + 4

3x + 12=3x + 4

3x + 12-12 = 3x + 4-12

3x= 3x-8

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
