Answer:
Step-by-step explanation:
Given is an equation in x and y as

We use implicit method to differentiate the above equation
18x-2yy'=0
y' = 9x/y
b) to solve the equation explicitly for y and differentiate to get y' in terms of x. y' = ±
We separate the variables as

Take square root

Answer:
The coordinates are (-8,7).
The required equation of the line is y = -1/2x
<h3>Equation of a line</h3>
The standard equation of a line is expressed as y = mx + b
- where:
- m is the slope
- b is the y intercept
Given the coordinate points (0,0) and (4, -2)
Slope = -2/4 = -1/2
The intercept is 0 since the line pass through the origin
Hence the required equation of the line is y = -1/2x

When given the scale factor and the factored size of the object, to find the original size, divide the factored size by the scale factor:
0.8 / 3.1 = 0.258 inches
The answer is 3/7 (Three over seven). You ADD the number of total possibilities (animal characters + human characters = 7 total characters) for the denominator and put in the number (or section) you're looking at as the numerator
