Suppose JK bisects angle LJM. The measure of angle LJK = (-10x + 3) and the measure of KJM = (-x + 21)º. Find the measure of ang

Over [174]

Well, take a look at this

-10x + 3 = -x + 21

+ 10 x +10x
--------------------------
3 = 9x + 21
-21 -21
---------------------
-18 = 9x
-2 = x

hope this helps

In Exercises 1–4, let S be the collection of vectors cxyd in R2that satisfy the given property. In each case, either prove thatS

Artyom0805 [142]

Answer:

S is not the subspace of $R^2$

Step-by-step explanation:

Let us suppose two vectors u and v belong to the S such that the property of xy≥0 is verified than

$u=\left[\begin{array}{c}-1 \\0\end{array}\right]$

$v=\left[\begin{array}{c}0 \\1\end{array}\right]$

Both the vectors satisfy the given condition as follows and belong to the S

$x_u y_u=-1\times 0=0 \geq 0\\x_v y_v=1\times 0=0 \geq 0\\$

Now S will be termed as subspace of R2 if

u+v also satisfy the condition
ku also satisfy the condition

Taking u+v

$u+v=\left[\begin{array}{c}-1 \\0\end{array}\right]+\left[\begin{array}{c}0 \\1\end{array}\right]\\u+v=\left[\begin{array}{c}-1+0 \\0+1\end{array}\right]\\u+v=\left[\begin{array}{c}-1 \\1\end{array}\right]$

Now the condition is tested as

$\\x_{u+v} y_{u+v}=-1\times 1=-1$

This indicates that the condition is not satisfied so S is not the subspace of $R^2$
