Your answer will be 1/55 or A because, at the beginning of the problem it states "you are one of 55 people" ((:
Answer:
I think it is b. Curve
Step-by-step explanation:
Answer:
y=-2x^2-4
Step-by-step explanation:
The parabola is wider than it's parent function, y = x^2. Therefore the coefficient, of x^2 (when you refer to quadratic equations it's a) should be greater than 1. Let's take 2.
y = 2x^2
Now it is reflected across the x-axis, so the equation turns to y = -2x^2. The vertex is shifted down 4. Note that it is shifted down, along the y-axis. This makes 'c' (again quadratic equations) -4.
Final Equation: y=-2x^2-4
The unit rate would be 3 trucks per 1 hour you can find this by dividing 18 and 6 by 6
