What is the simplified expression for the expression below? -1/5(5x+20)-1/4(4x-28) –2x + 3 –2x – 3 –2x – 8 –2x + 8

-2x+3

Step-by-step explanation:

You need to distribute the numerical factors for each term in the parenthesis:

This equals

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
