Answer:
<h2>Slope = 1/2</h2>Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
From the question the equation is
- 5x + 10y = 20
To find the slope we must first write the equation in the form above
- 5x + 10y = 20
Move - 5x to the right side of the equation
10y = 5x + 20
Divide both sides by 10
We have
Comparing with the general form of equation above
Slope / m = 1/2
Hope this helps you
Given:
u varies directly with the square of p and inversely with d.
To find:
The equation for the given situation.
Solution:
If y is directly proportional to x, then
If y is inversely proportional to x, then
It is given that u varies directly with the square of p and inversely with d. So,
It can be written as:
Where, k is the constant of proportionality.
Therefore, the required equation is .
