Answer:

$y=-\frac{5}{2}x+\frac{11}{4}$

Step-by-step explanation:

To find a line perpendicular to 2x - 5y = 20, we need to find the slope of the line. To get the slope, we can solve for y, and get the equation in the form of y=mx + b

So I will solve for y:

$2x - 5y = 20\\\\-5y=-2x+20\\\\y=\frac{2}{5} x-4$

So we know the slope is 2/5

The slope of a perpendicular line is the oposite reciprocal of original line. So the oposite reciprocal of 2/5 is -5/2. That will be our new slope

Now that we know the slope we can use the point slope formula to find an equation, then solve for y.

y-y₁=m(x-x₁)

y-4 = -5/2(x+ 1/2))

y= -5/2x + 11/4

If M is the centroid of triangle GHI, HL=45, JI=63, and KG=60, find the missing measures

AysviL [449]

Answer:

Part a) $ML=15\ units$

Part b) $HM=30\ units$

Part c) $JM=21\ units$

Part d) $MI=42\ units$

Part e) $GM=40\ units$

Part f) $MK=20\ units$

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

A <u><em>centroid</em></u> of a triangle is the point where the three medians of the triangle meet. A median of a triangle is a line segment from one vertex to the mid point on the opposite side of the triangle.

The centroid is located two thirds of the distance from any vertex of the triangle

Part a) Find ML

we have

$HL=45\ units$
