K is the midpoint of segment HL . H has coordinates (1, -7 ) , and K has coordinates(-9, 3 ). Find the coordinates of other end

Andrei [34K]

Answer:

Coordinates of other end point L = ( -19, 13 )

Explanation:

The mid point of the coordinates (a,b) and (c,d) is given by $(\frac{a+c}{2},\frac{b+d}{2})$

Here we have (a,b) = (1,-7) and $(\frac{a+c}{2},\frac{b+d}{2})$ = (-9,3) , we need to find (c,d).

$\frac{a+c}{2} =-9\\ \\ 1+c=-18\\ \\ c=-19\\\\ \frac{b+d}{2} =3\\ \\ -7+d=6\\ \\ d=13$

So coordinates of other end point L = ( -19, 13 )

Sara wants to find the input value that produces the same output for the functions represented by the tables.

Korolek [52]

Answer:

The input value that produces the same output value in both charts is 2.

Step-by-step explanation:

You are given two functions $f(x)=-0.5x+2$ and $g(x)=2x-3$ with tables

$\begin{array}{cc}x&f(x)\\-3&3.5\\-2&3\\-1&2.5\\0&2\\1&1.5\\2&1\\3&0.5\end{array}$

and

$\begin{array}{cc}x&g(x)\\-3&\\-2&\\-1&\\0&\\1&\\2&\\3&\end{array}$

First, fill in the second table:

$g(-3)=2\cdot (-3)-3=-6-3=-9\\ \\g(-2)=2\cdot (-2)-3=-7\\ \\g(-1)=2\cdot (-1)-3=-5\\ \\g(0)=2\cdot 0-3=-3\\ \\g(1)=2\cdot 1-3=-1\\ \\g(2)=2\cdot 2-3=1\\ \\g(3)=2\cdot 3-3=3$

Hence, the second table is

$\begin{array}{cc}x&g(x)\\-3&-9\\-2&-7\\-1&-5\\0&-3\\1&-1\\2&1\\3&3\end{array}$

The input value that produces the same output value in both charts is 2.
