If the width is w then the length = 2w + 40, so the area
= w(2w + 40)
= 2w^2 + 40 w
Answer:
That point would now be half as close to the origin, so (2,-1).
Slope AB = 1/3
slope CD = -3
Im not sure about the last part but I think the product of slope AB and slope CD is -1 so line AB is perpendicular to line CD.
the workings are below:)
(so sorry if it’s wrong)
Answer:
The equation of this line would be y = 4x - 5
Step-by-step explanation:
In order to find this equation we must first find the slope of the original line. The original slope (the coefficient of x) is 4, which means the new slope will also be 4 because parallel lines have the same slope. Now, we can use this slope along with the point in point-slope form to find the equation of the line.
y - y1 = m(x - x1)
y - 3 = 4(x - 2)
y - 3 = 4x - 8
y = 4x - 5
