Hello : 
\frac{5}{a} - \frac{2}{1-a} = \frac{2}{a-1} = \frac{5}{a}+ \frac{2}{a-1} = \frac{2}{a-1}
= \frac{5(a-1)+2a}{a(a-1)} = \frac{2a}{a(a-1)} 
(a \neq 1  ,  a \neq 0)

5a-5 +2a =2a
5a =5
a=1 ( refused)
conclusion : <span>none</span>

Polygon ABCD, shown in the figure, is dilated by a scale factor of 8 with the origin as the center of dilation, resulting in the
saveliy_v [14]
C = (5,4)

D = (4,2)

Dilation with factor 8 => for the same x, y increase by a factor of 8

=> C' = (5, 8*4) = (5, 32)

=> D' = (4, 8*2) = (4, 16)

slope of C'D' = [32 - 16] / [5 -4 ] =16

You can also see that the slope of CD = [4 - 2] / [5 - 4] = 2

Then, the new slope is 8 times the old slope, this is it was multiplied by the same factor, 8.

8.5x+51.86=-11.5x+51.76
solniwko [45]
Add, -11.5x and move it over to 8.5x

Then, subtract them together and you get 20x + 51.86 = 51.76

And you move (subtract) 51. 86 over to 51.76, subtract that and you get             20x = -0.1

Divide, and your answer is -200
