In the above figure, m∠A = 20° and m∠B = 2x + 18. If angles A and B are complementary angles, what are the value of x and the measure of angle B?
A. x = 71, m∠B = 160°
B. x = 26, m∠B = 52°
C. x = 26, m∠B = 70°
D. x = 46, m∠B = 70°

answer: it is a.,b.,d.

step-by-step explanation:

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
