<span>By similarity of triangles we have the following relationship:</span>
<span> (x) / (6) = (18) / (9)</span>
<span> Simplifying we have:</span>
<span> (x) / (6) = 2</span>
<span> Clearing the value of x we have:</span>
<span><span> x = 6 * 2</span></span>
<span><span> X = 12</span></span>
<span><span> Answer:</span></span>
<span><span> The value of x for this case is equal to:</span></span>
<span><span> <span>X = 12</span></span>

Answer:
Step-by-step explanation:
The range of a function y = f(x) is the set of values y takes for all values of x within the domain of f. The graph of any quadratic function, of the form f(x) = a x2 + b x + c, which can be written in vertex form as follows. f(x) = a(x - h)2 + k where h = - b / 2a and k = f(h) is either a parabola opening up, when a > 0, or a parabola opening down, when a < 0
Question 1:
x - Tim`s age, y - Coach Johnson`s age:
x + 10 = y
2 * ( x - 3 ) = y - 3
-----------------------
2 x - 6 = x + 10 - 3
2 x - x = 7 + 6
x = 13
Tim is 13 years old.
Question 2:
x - 62,500 = 0.25 * 125,000
x - 62,500 = 31,250
x = 31,250 + 62,500
x = 93,750
