In a diagram, X is the midpoint of Segment VZ. VW =5, and VY =20. Find the coordinates of W,X, and Y.
guapka [62]

solution:

x(a_{x},b_{x})is midpoint of vz\\
a_{x}=\frac{a_{v}+a_{z}}{2}=\frac{-12+22}{2}=\frac{10}{2}=5\\
b_{x}=\frac{b_{v}+b_{z}}{2}=\frac{0+0}{2}=0\\
and,\\
x(5,0)\\
w(a_{w},b_{w}),v_{w} and w is on the right of v.\\
a_{w}-a_{v}=5\\
a_{w}-(-12)=5\\
a_{w}+12=5\\
a_{w}=5-12=-7\\
w(-7,0)\\
y(a_{y},b_{y})=20 and y is on the right of v.\\
a_{y}-a_{v}=20\\
a_{y}-(-12)=20\\
a_{y}+12=20\\
a_{y}=20-12=8\\
y=(8,0)

1/4(1-2/3)^2+1/3 Simplify
MrMuchimi

Simplifying the expression gives 13/ 36

<h3>How to solve the expression</h3>

Given;

1/4(1-2/3)^2+1/3

Represented as;

\frac{1}{4} * ( 1  - \frac{2}3} )^2 + \frac{1}{3}

Take the LCM of the bracket

\frac{1}{4} * ( \frac{1}{3} )^2 + \frac{1}{3}

Find the square

\frac{1}{4} (\frac{1}{9} )+ \frac{1}{3}

Find the LCM

\frac{1}{36} + \frac{1}{3}

1 + 12/36

13/ 36

Thus, simplifying the expression gives 13/ 36
