27x - 144 + 15 = 6x - 24
27x - 129 = 6x - 24
       +129         +129
      ---------      --------
           0            105
27x = 6x + 105
-6x    -6x
-----  ------
 21x    0

21x = 105

21x/21 = 105/21

x = 5

Remove brackets
Gather like terms
Get rid of the lone number
Transfer
Divide

Hope this helps :)

A) part of it is decreasing, part of it is increasing.  

Going left-to-right, the downhill/negative slope is the decreasing portion (x<-1) and the uphill/positive slope is the increasing portion (x>-1).  

B) The x-intercepts are the points where the graph intersects the x-axis: (2,0) and (-4,0).

C: The y-intercept is the point where the graph intersects the y-axis: (0,-2).

D: There is no absolute maximum.  The graph keeps going up forever.

E: The absolute minimum <u>point</u> is at that bottom, at (-1, -3).  The absolute minimum <u>value</u> is -3, since that's the lowest y-value used.

Answer:

Option A is correct.

Step-by-step explanation:

If Δ YES ∼ Δ NOT, then it means that ΔYES and ΔNOT are similar triangles.

The similar triangles means that all the corresponding angles of the two triangles are same i.e. ∠ Y = ∠ N, ∠ E = ∠ O and ∠ S = ∠ T

Therefore, according to the property of similar triangles we can write that

\frac{NO}{YE} = \frac{OT}{ES}  = \frac{NT}{YS}.

Therefore, option A is correct.
