Answer:

45°

Step-by-step explanation:

Angles in a triangle add to 180 degrees, so

2x - 12 + 2x + 17 + 9x - 7 = 180
13x - 2 = 180
13x = 182
x = 14

So, the measure of angle X is 2(14)+17=45°

Write a polynomial function with the zeros 1, -2i

Helga [31]

F( x ) = ( x - 1 ) ( x + 2i )( x - 2i ), because the zeroes are 1, -2i, +2i ;
f( x ) = ( x - 1 )( x^2 - 4i^2 ) = ( x - 1 )( x^2 + 4 ) = x^3 - x^2 + 4x - 4 ;

Y=-3 - x, how to draw the graph

adell [148]

Answer: See attachment below (graphing)

Step-by-step explanation:

INFORMATION:

The slope-intercept is when y=mx+b

mx=the slope

b=y-intercept

REPHRASE EQUATION:

y=mx+b

y=-3-x

y=(-1)x-3

CONCLUSION:

Slope=-1

Y-intercept=-3

Hope this helps!! :)
