Answer:
The equation is an differential equation of second order.
The dependent variable is x, while t is the independent variable.
Step-by-step explanation:
The order of the equation depends on the greatest grade of the derivative, in this case it's the second derivative (x'')
Since x is a function of t, we would have that t is the independent variable while x is the dependent variable.
Answer:y=3/2x-3
Step-by-step explanation: the slope of the graph is (y2-y1)/(x2-x1)
If we take points (0,-3) (2,0) the slope would be (0--3)/(2-0) = 3/2
And the y-intercept of the slope is -3
Answer: The last one
Step-by-step explanation: The data is all between 4 and 7 and there are no gaps. The max is 7 dollars as stated.
4 / 1 = 1 / x....4 miles to 1 hr = 1 miles = x hrs
cross multiply
4x = 1
x = 1/4.....it would take 1/4 of an hr (or 15 minutes) to walk 1 mile
