Floor(0) -3 = -3 . . . . . only the left-side graphs have this point
floor(0.1) -3 = -3 . . . . only the lower-left graph has this point.
The lower-left selection is appropriate.
C= 1,800- dailey fixed cost
2,200 (x) pianos in one day
c= 1,800 +2,200 (2)=

Answer:
Dividing in unit form
9 ten thousand = 9 × 10000 = 90000
90000 ÷ 10 = 9000
Dividing the sum in Standard Form
90000 = 9 × 10⁵
10 = 10¹
[9 × 10⁵] ÷ 10¹ = 9 × 10
Just find the roots of the quadratic equation. The x - intercepts will be the same value as the roots . Or you can say that x - intercepts are the roots of the equation only
