To solve for the variable algebraically and make the sentence below true, what should be done to both sides of the inequality?
9> x+3

a. 3 should be added to both sides
b. divide both sides by 3
c. subtract 3 from 9 only
d. subtract 3 from both sides.

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

step-by-step explanation:

the square root of 16 is 4.

4*4 = 16
