Answer: A
Step-by-step explanation:
We need to get the denominators to be same first before we can do anything to the numerator.
<em>The LCD (lowest common denominator) is </em><em>. To find the LCD, multiply the denominators together: </em><em> · </em><em> = </em>.
Below, we are trying to get the denominators to equal the same or to .
Now that the denominators are the same, we can subtract the numerators from each other.
Now, we can just reorganize the variables.

Answer:
y=
Step-by-step explanation:
switch the x and y and solve for y.
11.
Given:
Differentiate with respect to x, we get
The given point is (3,9)
Substitute x=3 in the derivative, we get
Hence the slope is 3.

Given:
Differentiate with respect to x, we get
The given point is (0,4)
Substitute x=0 in the derivative, we get
Hence the slope is 0.
