The equation of the diameter which bisects the chord with slope 1/2 is
The general form of the equation of given ellipse is and equation of chord will be for some m and n.
Now in order to find values of x that intercept the ellipse it must fulfill the equation as such;
<h3 /><h3>What is the definition of an ellipse?</h3>
It is a plane section curve whose sum from two fixed points will be a constant value.
Quadratic roots will give the mid value of x and value of y will be ;
Thus the final equation of required diameter will be :
And in this case the equation of the diameter which bisects the chord with slope 1/2 is,

Answer:
30 = 9x + 7
Step-by-step explanation:
The total weight of the bundle = 30 pounds
The weight of the bricks = x pounds
But he carried 9 bricks = 9x pounds
He also carried additional 7 pounds of concrete block.
An equation to show the total weight he carried is
30 pounds = (9x + 7) pounds
Since 9x represents the total weight of the bricks he carried
7 represents the weight of the concrete block
And 30 pounds represents the total weight of everything he carried.
