Answer:
-5/4
Step-by-step explanation:
Divide both sides by -4
y= -5x/4 -6/4
Simplify, y= -5x/4 -3/2
Slope = -5/4
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:

Step-by-step explanation:

Make sure they have a common denominator. To do so, you must find a number the both have in come. Here, the number they have in common is 20.
What times 4 equals 20? 5. Whatever you do to the denominator you must do to the numerator.
×
= 
Now you have
= 
Then you can simplify
to
by dividing it by 
The sum of the 3 angles of a triangle is 180 °
the sum of the arc of a circle is 360°
⇒ the inscribed angle = the angle measure of the arc it intercepts/2
