Which ordered pair (p, n) is the solution to the given system of linear equations? {5p - 3r = 1
{8p + 6r = 4

• (-1, -2)

O (-2, -1)

O ( 2/9 , 1/3 )

O ( 1/3 , 2/9 )

the second one(-2.-1

Step-by-step explanation:

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5

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
