-1.75 is greater than-3.25 because -1.75 is closer to 0.
Answer:
<em>The x-coordinate is changing at 10 cm/s</em>
Step-by-step explanation:
<u>Rate of Change</u>
Suppose two variables x and y are related by a given function y=f(x). If they both change with respect to a third variable (time, for instance), the rate of change of them is computed as the derivative using the chain rule:

We have

Or, equivalently

We need to know the rate of change of x respect to t. We'll use implicit differentiation:

Solving for dx/dt

Plugging in the values x=1, y=3, dy/dt=5

The x-coordinate is changing at 10 cm/s
Answer
8 is not greater than 10
Step-by-step explanation:
2x>10
2(4)>10
8<10
x=4 can not be the solution to this equation because 8 is less than 10
*just as a side note think of the > sign as an alligator, the mouth always is open towards the larger number
(6x-12)/10 factor out 2
2(3x-6)/(2(5))
(3x-6)/5 and you can factor out 3 from the numerator too
3(x-2)/5 which can be expressed as:
0.6(x-2)
