The domain of the question you are asking is (-∞,∞)
Yes you can assume they are similar because the sides that correspond with one another are half of the big triangles measurements. 16/2=8 12/2=6 etc.

124 males watching a drama divided by 479 the total amount of people = 0.26
Concerning the interrogate, the retort to such is identified as the following,,
Convert the Slope-Intercept Form to General Form:
Y = -2x - 9 ==> 2x + y = -9
Evaluate:
2x + y = -9
2x + 3y = -9
Multiply the X factors by each other, making one of the products opposite:
-2(2x + y) = -9 ==> -4x - 2y = 18
2(2x + 3y) = -9 ==> 4x + 6y = -18
Add the expressions:
-4x - 2y = 18
4x + 6y = -18
————————
4y = 0
Y = 0
Now, substitute the zero within one of the equations:
2x + 3y = -9
2x + 3(0) = -9
2x = -9
X = -4.5
Thus, (-4.5,0)
