Answer:

1,2

Step-by-step explanation:

R is 2 to the left and 1 up from the origin. If you rotate that 90 degrees its 2 up and 1 to the right.

I need help with this graph.

tatuchka [14]

Two parallel lines never intersect, therefore they will never have a solution.

One line could be x=6 and the other could be x=2

Hope this helps :)

let t : r2 →r2 be the linear transformation that reflects vectors over the y−axis. a) geometrically (that is without computing a

tangare [24]

(a) ( 1, 0 ) is the eigen vector for '-1' and ( 0, 1 ) is the eigen vector for '1'.

(b) two eigen values of 'k' = 1, -1

for k = 1, eigen vector is $\left[\begin{array}{c}0\\1\end{array}\right]$

for k = -1 eigen vector is $\left[\begin{array}{c}1\\0\end{array}\right]$

See the figure for the graph:

(a) for any (x, y) ∈ R² the reflection of (x, y) over the y - axis is ( -x, y )

∴ x → -x hence '-1' is the eigen value.

∴ y → y hence '1' is the eigen value.

also, ( 1, 0 ) → -1 ( 1, 0 ) so ( 1, 0 ) is the eigen vector for '-1'.

( 0, 1 ) → 1 ( 0, 1 ) so ( 0, 1 ) is the eigen vector for '1'.

(b) ∵ T(x, y) = (-x, y)

T(x) = -x = (-1)(x) + 0(y)

T(y) = y = 0(x) + 1(y)

Matrix Representation of $T = \left[\begin{array}{cc}-1&0\\0&1\end{array}\right]$

now, eigen value of 'T'

$T - kI = \left[\begin{array}{cc}-1-k&0\\0&1-k\end{array}\right]$

after solving the determinant,

we get two eigen values of 'k' = 1, -1

for k = 1, eigen vector is $\left[\begin{array}{c}0\\1\end{array}\right]$

for k = -1 eigen vector is $\left[\begin{array}{c}1\\0\end{array}\right]$

Hence,

(a) ( 1, 0 ) is the eigen vector for '-1' and ( 0, 1 ) is the eigen vector for '1'.

(b) two eigen values of 'k' = 1, -1

for k = 1, eigen vector is $\left[\begin{array}{c}0\\1\end{array}\right]$

for k = -1 eigen vector is $\left[\begin{array}{c}1\\0\end{array}\right]$

Solve the inequality<br> 3/10 ≥ k - 3/5

balandron [24]

Answer:

The answer to your question is $k \leq \frac{9}{10}$ or (-∞ , 9/10]

Step-by-step explanation:

To solve inequality is similar to solve and equation, we just need to find the values of "k" in order than the inequality be true.

$k - \frac{3}{5} \leq \frac{3}{10}$

Solve for "k"

$k \leq \frac{3}{10} + \frac{3}{5}$

$k \leq \frac{3}{10} + \frac{6}{10}$

$k \leq \frac{9}{10}$

Then the answer is

$k \leq \frac{9}{10}$ or (-∞ , 9/10]

Bailey just ran four miles outside. Her time for each mile was 9.05 / 8.24 / 10 / 9.22. How long did it take for her to run all

larisa86 [58]

Answer:

36.51

Step-by-step explanation:

If Bailey ran four miles, then the time that is given for each of her miles should be added together to find out her total time.

9.05 + 8.24 + 10 + 9.22

You can break it down into chunks to make it easier for you:

9.05 + 8.24

= 17.29

___________

9.22 + 10

= 19.22

_________________________________________________

Then you can just add both values together to find out the total

_________________________________________________

17.29 + 19.22 = 36.51
