Absolute value means ignore negative signs, so #38 is asking is 282 greater or less than 279. it's greater. #39 is negative of |-10| the absolute value signs work as parentheses too, so it's -(10) so -10

What is the graph of the function rule Y= 1/3x - 1 ?

GrogVix [38]

Yes. A is the right graph because the line must travel through two points: (0 ,1)and(-3, 0)

The graph of y=1/x is shown below. Draw the graph of its inverse.

lord [1]

Y=1/x solve for x

x=1/y now reverse lables...

y=1/x

Yes that is the same equation you started with. What that means is the the inverse function in this case produces the same exact graph :)

Answer:

(a, b) = (-2, -1)

Step-by-step explanation:

The transpose of the given matrix is ...

$A^T=\left[\begin{array}{ccc}1&2&a\\2&1&2\\2&-2&b\end{array}\right]$

Then the [3,1] term of the product is ...

$(A\cdot A^T)_{31}=\left[\begin{array}{ccc}a&2&b\end{array}\right]\cdot\left[\begin{array}{ccc}1&2&2\end{array}\right]=a+2b+4$

and the [3,2] term is ...

$(A\cdot A^T)_{32}=\left[\begin{array}{ccc}a&2&b\end{array}\right]\cdot\left[\begin{array}{ccc}2&1&-2\end{array}\right]=2a-2b+2$

Both of these terms in the product matrix are 0. We can solve the system of equations by adding these two terms:

(a +2b +4) +(2a -2b +2) = (0) +(0)

3a +6 = 0

a = -2

Substituting for 'a' in term [3,1] gives ...

-2 +2b +4 = 0

b = -1

The ordered pair (a, b) is (-2, -1).

Mike had 5 5/6 he gave 11/6 to mathew and 4/6 to nolan and 3/4 to sanjar how much does mike have now

dexar [7]

Find a common denominator or the bottom number of a fraction. 5 and 5/6 - 11/6 - 4/6 - 3/4 = 140/24 - 44/24 - 16/24 - 18/24 = 96/24 - 16/24 - 18/24=62/24 or 2 and 7/12.
