Step-by-step explanation:

3      -4    |   2

0      -1     |   7

3/2    -2    |   1

R1/3 ----> R1  (divide Row 1 by 3)

1       -4/3    |  2/3

0        -1      |   7

3/2      -2     |   1

R3 - 3/2  R1 -------> R3 (multiply Row 1 by 3/2 and subtract it from Row 3)

1      -4/3    |   2/3

0       -1      |    7

0       0      |    0

R2 / -1 -------> R2 (Divide Row 2 by -1)

1      -4/3   |  2/3

0        1     |   -7

0        0    |   0

R1 + 4/3 R2 --------> R1 (Multiply Row 2 by 4/3 and add it to Row 1)

Mutleys journey began on a boat, 2 feet above sea level. He dove down to twelve feet below sea level and then returned to the su
Lubov Fominskaja [6]

Answer:

Mutley would start at 2 feet above sea level or +2, he would then travel 12 feet below sea level (-12) to then return to the surface of the ocean (0).  The integers from least to greatest:  -12, 0, 2.  Visual:

-12(dive level) * * * * * * * * * * * 0(sea level) * 2(boat)

Step-by-step explanation:

Using positive and negative integers, we can determine Mutleys journey above, below and at the surface of the ocean.  The surface of the ocean represents his 'origin' or starting point, which is 0.  The boat is above the surface or +2.  When Mutley dives below the surface, he is at a negative level of the ocean.  Think of it in terms of a number line - negative numbers are to the left of 0 and positive numbers are to the right of 0.  The further we go to the left on the number line, the lower our number.  In this case, -12 would be furthest to the left, then 0, followed by 2.

Which of the following function types exhibit the end behavior (PICTURE INCLUDED)
Nostrana [21]

Answer:

y=x^n; n is even and greater than zero.

The absolute value function y=|x|

Step-by-step explanation:

The power function;

y=x^n; n is even and greater than zero, is symmetric with respect to the positive y-axis.

As x\rightarrow \infty,f(x)\rightarrow \infty and as x\rightarrow -\infty,f(x)\rightarrow \infty

The absolute value function y=|x| also has the same end behavior.

The remaining functions in the options provided do not exhibit this end behavior.

See graph in attachment.

For his job at the hardware store, Michael distributes 2,345 packages of screws into 5 equal groups for shipping. How many packa
drek231 [11]

\\
\text{Michael distrinutes  2345 packages of screws into 5 equal groups for shipping.}\\
\\
\text{we need to find the number of packages of screws in each group.}\\
\\
\text{so for this we use the unitary method.}\\
\\
\text{The number of packages of screws in 5 groups}=2345\\
\\
\text{so the number of packages of screws in 1 group}=\frac{2345}{5}\\
\\
=469

Hence the number of packages of screws in each shipping box is: 469

Hence option (B) is correct.
