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

1 million has 6 zeros after it.
Yeah i agree with them y=10
Answer: 18.68
Step-by-step explanation:
The x intercept of the given line is (10, 0)
<h3>Finding the x intercept of a line</h3>
The x intercept of a line is the point where the line crosses the x-axis
It is the point where the value of y is zero
Given the equation of a line -2x+5y = -20
Substitute y = 0 into the equation
-2x +5(0) = -20
-2x = -20
x = 10
Hence the x intercept of the given line is (10, 0)
