Given the system {4x-y+2z=-1 -x+2y+5z=2 -x+y-3z=1, which is true?
a. the system has no solutions
b. the system has exactly one solution
c. the system has exactly three solutions
d. the system has an infinite number of solutions

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

what are the

the answer to this is 4340

hope this if needed hmu

d will be the best answer
