y = something x plus or minus a number

going through each line it isn't a linear pattern ( they don't all have the same difference when subtracted or added together)

so now you play around with quadratic equations ( square roots, powers, etc.)

and you will see that y = x^2 -5

Represents a coefficient from the expression given? 9x – 20 + x2

yanalaym [24]

Answer:

$(x - \frac{ - 9 + \sqrt{161} }{2} )(x - \frac{ - 9 - \sqrt{161} }{2} )$

Step-by-step explanation:

$1. \: a(x - \frac{ - b + \sqrt{ {b}^{2} - 4ac} }{2a} ) \: (x - \frac{ - b - \sqrt{ {b}^{2} - 4ac} }{2a}) \\ 2. \: (x - \frac{ - 9 + \sqrt{ {9}^{2} - 4 \times - 20 } }{2} ) \: (x - \frac{ - 9 - \sqrt{ {9}^{2} - 4 \times - 20 } }{2} )$

Angle abc and dcb make a linear pair. of abc=2x+9 and dbc=10x+15,find x

Anuta_ua [19.1K]

Answer:

x = 13

Step-by-step explanation:

A linear pair of angles sum to 180° , then

2x + 9 + 10x + 15 = 180 , that is

12x + 24 = 180 ( subtract 24 from both sides )

12x = 156 ( divide both sides by 12 )

x = 13
