G(x) = G(1/2)
So just plug in
20(1/2) - 189
10-189
= -179
Your final answer is -179
Hope this helped! Let me know if you have any questions.

Answer:
The value of the expression at b = -2 is thus -6
Step-by-step explanation:
We have been given the expression;
and we are required to evaluate the expression for b = -2
We simply substitute b with -2 in the given expression and simplify;
Sarah's 10 years old.
Antonio's 2 years old.
2 x 2 = 4
10 x 3 = 30
4 + 30 = 34
2 x 5 = 10
To find the equation of a line using two coordinate points, use the slope intercept formula, (y2-y1)/(x2-x1). Using this formula, plug in your values from the two coordinates (-5, -5) and (1, -3). This would look like this:
(-3-(-5))/(1-(-5))
When simplified, you should get 2/6 or 1/3 as your slope or m value. Now that you have your slope, now use your slope intercept equation y=mx+b and plug in your known values. Since you know the m value is 1/3 and you can use one of your set of points to plug into the x and y values, you can plug in these values and solve for b (the coordinate you use doesn't matter but I'm just using the (1,-3)). This would look like this:
-3=1/3(1)+b
When you simplify, you should get -3=1/3+b and when you subtract both sides by 1/3, you should get b=-10/3.
Now that you have your m and b values, you can conclude that your equation for the line would be y=1/3x-10/3
