Let's find the derivative of that hyperbola in order to find a slope formula to help us with this equation. We already have an x and y value. The derivative is found this way:

so

. The derivative supplies us with the slope formula we need to write the equation. Sub in the x value of 3 to find what the slope is:

. So in our slope-intercept equation, x = 3, y = 1, and m = -1/3. Use these values to solve for b.

so b = 2. The equation, then, for the line tangent to that hyperbola at that given point is
<span>The tortoise is runing one mile per hour the entire race.
The hare is runing 3/4 only the first half.
If we multiply by 2 totis =2 miles and hare =1.50 the hare need to run 1/2 or .50 faster to beat the tortis.</span>
It's 4y because it is multiplying, meaning it does not matter the order of the numbers and variables.
Answer:
If you have a perpendicular shape, like a plus sign, usually what I was taught, right whole side of the "plus" sign are negative. The left side is positive. I think it's how you say it.
So first, you have to multiply 2.2 x 1000000 = 2200000, next you need to multiply 4.3 x 100000 = 430000, lastly, you subtract 2200000 - 430000 = 1770000
