Which could be the first step of an indirect proof of the conditional below? Select all that apply. If x = 4, then 4x = x2.

A. If 4x ≠ x2, then x ≠ 4.
B. If x = 4, then 4x = x2.
C. Assume if 4x ≠ x2, then x ≠ 4.
D. Assume if x ≠ 4, then 4x ≠ x2.

A. If 4x ≠ x2, then x ≠ 4.  &  D. Assume if x ≠ 4, then 4x ≠ x2.

Step-by-step explanation:

i took the test and it was not  B;If x = 4, then 4x = x2. or C;Assume if 4x ≠ x2, then x ≠ 4.

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
