12 out of 36 is the same as 12/36
Both 12 and 36 are divisible by 12.
12/36 = (1 * 12)/(3 * 12) = 1/3 * 12/12 = 1/3 * 1 = 1/3
Answer: 1/3
5(4x-3)^2 - 3
5(16x^2 - 2(3)(4x) + 9) -3
5(16x^2 - 24x + 9) -3
80x^2 - 120x + 45 - 3
80x^2 - 120x + 42
80(0)^2 - 120(0) + 42
42
Since we know that the ratio of the model car to the real
car is 1:64, therefore we use this to solve this true length of the real NASCAR
vehicle, let us call this us X, so that:
1 : 64 = 3 inches : X
1 / 64 = 3 inches / X
X = 192 inches

The true length is 192 inches</span>
Here's all I can think of:
f(0) = -10. This is the y-intercept of this parabolic graph. This point is (0,-10).
If you were to find the inverse of f(x), then (-10,0) would be on the graph.
