Step-by-step explanation:
<span>All real numbers that are greater than –6 but less than 6 is written as -6 < x < 6</span>
Answer:
False
Step-by-step explanation:
Pos and negs cannot be perfect square trinomials
T is a linear transformation from R²→R² with basis {(1,0),(0,1)}
T: (x,y)→(x+6,y+4)
A function from one vector space to another that preserves the underlying (linear) structure of each vector space is called a linear transformation.
Then the vector (1,0) goes to (1+6,4)=(7,4)=7(1,0)+4(0,1)
and the vector (0,1) goes to (6,1+4)=(6,5)=6(1,0)+5(0,1)
So, the matrix of the transformation is
![\left[\begin{array}{ccc}7&6\\4&5\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D7%266%5C%5C4%265%5Cend%7Barray%7D%5Cright%5D)
The inverse of the matrix is
![\left[\begin{array}{ccc}\frac{5}{11}&\frac{-6}{11}\\ \\\frac{-4}{11}&\frac{7}{11}\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D%5Cfrac%7B5%7D%7B11%7D%26%5Cfrac%7B-6%7D%7B11%7D%5C%5C%20%5C%5C%5Cfrac%7B-4%7D%7B11%7D%26%5Cfrac%7B7%7D%7B11%7D%5Cend%7Barray%7D%5Cright%5D)
So, the Inverse Transformation is given by
![T^{-1}(x,y)=\left[\begin{array}{ccc}\frac{5}{11}&\frac{-6}{11}\\ \\\frac{-4}{11}&\frac{7}{11}\end{array}\right]\left[\begin{array}{ccc}x\\y\end{array}\right] =(\frac{5x-6y}{11}, \frac{-4x+7y}{11})](https://tex.z-dn.net/?f=T%5E%7B-1%7D%28x%2Cy%29%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D%5Cfrac%7B5%7D%7B11%7D%26%5Cfrac%7B-6%7D%7B11%7D%5C%5C%20%5C%5C%5Cfrac%7B-4%7D%7B11%7D%26%5Cfrac%7B7%7D%7B11%7D%5Cend%7Barray%7D%5Cright%5D%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7Dx%5C%5Cy%5Cend%7Barray%7D%5Cright%5D%20%3D%28%5Cfrac%7B5x-6y%7D%7B11%7D%2C%20%5Cfrac%7B-4x%2B7y%7D%7B11%7D%29)

Answer:
x = -7/40
, y = -11/20
Step-by-step explanation:
Solve the following system:
{12 x - 2 y = -1 | (equation 1)
4 x + 6 y = -4 | (equation 2)
Subtract 1/3 × (equation 1) from equation 2:
{12 x - 2 y = -1 | (equation 1)
0 x+(20 y)/3 = (-11)/3 | (equation 2)
Multiply equation 2 by 3:
{12 x - 2 y = -1 | (equation 1)
0 x+20 y = -11 | (equation 2)
Divide equation 2 by 20:
{12 x - 2 y = -1 | (equation 1)
0 x+y = (-11)/20 | (equation 2)
Add 2 × (equation 2) to equation 1:
{12 x+0 y = (-21)/10 | (equation 1)
0 x+y = -11/20 | (equation 2)
Divide equation 1 by 12:
{x+0 y = (-7)/40 | (equation 1)
0 x+y = -11/20 | (equation 2)
Collect results:
Answer: {x = -7/40
, y = -11/20
