F(x) = 2x2 – 4x – 3 0 = 2x2 – 4x – 3 3 = 2(x2 – 2x) 3 + 1 = 2(x2 – 2x + 1) 4 = 2(x – 1)2 2 = (x – 1)2 ± = x – 1 1 ± = x mica is solving for the zeros of a quadratic function by completing the square. her work is shown. what error did mica make? answer choices mica should have set each x = 0 instead of f(x). mica should have added 2 to 3 instead of 1. mica should have multiplied both sides by 2 instead of dividing. mica should have subtracted 1 from both sides instead of adding.

step-by-step explanation:

im not sure but my dad knows

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
