MAVERICK [17]

Answer:

1.5 meters

Step-by-step explanation:

the fabric is 4 meters long

first piece is 1.25 meters long

second piece will be (4-1.25)=2.75 meters long

Write the equation of a line that is perpendicular to the given line and that passes through the given point.
Firlakuza [10]

Answer:

y - 3 = (5/3)(x - 6)

Step-by-step explanation:

The usual first step is to determine the slope of the given line.

In this case the slope is -3/5.

A line perpendicular to this given line would have a slope of 5/3, which is the negative reciprocal of -3/5.

This new line goes thru (6, 3) and has a slope of 5/3.  Thus, the equation of the line in point-slope form is

y - 3 = (5/3)(x - 6)

Double check that you have copied the problem down correctly.  The slope of the line represented by -3x - 5y = 17 is neither 2 nor -2; it is -3/5, and so the slope of a line perpendicular to -3x - 5y = 17 is +5/3.

The endpoints of a side of rectangle ABCD in the coordinate plane are at A(3, 5) and B(5, 1). Find the equation of the line that
andreyandreev [35.5K]

Answer:

2x + y = 16

Step-by-step explanation:

In rectangle side AB and side CD are parallel, so the slope of both the lines will be same it means that they are parallel to each other.

slope of line AB:

\textrm{m}=\frac{\textrm{y}_{A}-\textrm{y}_{B}}{\textrm{x}_{A}-\textrm{x}_{B}}\\\textrm{m}=\frac{5-1}{3-5}=\frac{4}{-2}=-2\\\therefore \textrm{m}=-2

slope of line CD = slope of line AB = -2

∴ equation of line CD:

\textrm{y}-\textrm{y}_{C}=\textrm{m}(\textrm{x}-\textrm{x}_{C})\\ \textrm{y}-2=-2(\textrm{x}-7)\\2\textrm{x}+\textrm{y}=16
