Answer:
After 16 weeks she will have 145 dollars left in her account.
Step-by-step explanation:
since 145 represents the amount of money in her account we will substitute that for "y" and solve for "x"
145=-27x+577
145-577=-27x
-432=-27x
-432/-27= -27x/-27
16=x
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
