Simplify the expression where possible. (t 9) -8

makvit [3.9K]

Answer:

$\frac{1}{t^{72}}$ .

Step-by-step explanation:

To solve this problem, we need to simplify the expression $(t^{9})^{-8}$ .

We know that $(x^{a})^{b} = x^{ab}$

Therefore:

$(t^{9})^{-8} =t^{-72} =\frac{1}{t^{72}}$ .

How do I solve this out??

GuDViN [60]

<h3>Answer:</h3>

(x, y) = (7, -5)

<h3>Step-by-step explanation:</h3>

It generally works well to follow directions.

The matrix of coefficients is ...

$\left[\begin{array}{cc}2&4\\-5&3\end{array}\right]$

Its inverse is the transpose of the cofactor matrix, divided by the determinant. That is ...

$\dfrac{1}{26}\left[\begin{array}{ccc}3&-4\\5&2\end{array}\right]$

So the solution is the product of this and the vector of constants [-6, -50]. That product is ...

... x = (3·(-6) +(-4)(-50))/26 = 7

... y = (5·(-6) +2·(-50))/26 = -5

The solution using inverse matrices is ...

... (x, y) = (7, -5)

Translation: 6 units right and 3 units down<br> s(-3, 3), C(-1, 4), W(-2,-1)

sdas [7]

S (3, 0)
C (5, 1)
W (4, -4)

Explanation
You take the first number and add 6 to it and you get the new number and then you take the second number and subtract 3 from it

S: -3 + 6 = 3
S- 3 - 3 = 0

C: -1 + 6 = 5
C: 4 - 3 = 1

W: -2 + 6 = 4
W: -1 - 3 = -4
