Answer:

Second graph

Step-by-step explanation:

Given inequality,

| x + 7 | - 2 ≥ 0

| x + 7 | ≥ 2

x + 7 ≥ ± 2

x ≥ -7 ± 2

⇒ x ≥ -7 + 2 or x ≥ -7 - 2

⇒ x ≥ -5 or  x ≥ -9,

Thus, in the shaded region x ≥ -5 or  x ≥ -9,

In the given graphs, the shaded region represents by green,

In the first graph, green line lies in the region -9 ≤ x ≤ -5

Thus, it can not be the graph of the given inequality,

In the second graph, green line lies in the region  x ≥ -5 or  x ≥ -9

Hence, second graph would be the answer.

Solve the following system of equations for all three variables.
GrogVix [38]

Answer:

(x,y,z) -> (2,4,1)

Step-by-step explanation:

-7x + y + z = -9

-7x + 5y - 9z = -3

7x - 6y + 4z = -6

Pick two pairs:

-7x + 5y - 9z = -3

7x - 6y + 4z = -6

and

-7x + y + z = -9

-7x + 5y - 9z = -3

Eliminate the same variable from each system:

-7x + 5y - 9z = -3

7x - 6y + 4z = -6

+ 5y - 9z = -3

- 6y + 4z = -6

<u><em>-1y - 5z = - 9</em></u>

-7x + y + z = -9

-7x + 5y - 9z = -3

-7x + y + z = -9

7x - 5y + 9z = 3

<u><em>-4y - 10z = -6</em></u>

Solve the system of the two new equations:

-1y - 5z = - 9           ->      -4 ( -1y - 5z = - 9)     ->   4y + 20z = 36  

-4y - 10z = -6          ->           -4y - 10z = -6      ->   -4y - 10z = -6

10z = 30

Thus, z = 3

-4y - 10z = -6

-4y - 10(3) = -6

-4y - 30 = -6

-4y = 24

Thus, y = -6

Substitute into one of the original equations:

-7x + y + z = -9

-7x + (-6) + (3) = -9

7x + -3  = -9

7x  = -6

x =

HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

A circle is 360°. Since you only have 3 different types of weather, if you split the ° equally, each section would have 120°. The amount of rainy days is 10/30 or exactly 1/3, so 120° are rainy days.

If you do 30 x 12, it equals 360. So that means that each day is 12°. There were 8 cloudy days, so you can do 8 x 12 = 96°

Yousef borrowed 1,690 last term for tuition, books, and student fees. This term he plans to borrow 2,345 because he knows his cl
motikmotik

The estimate of the amount of money Yousef will borrow by first rounding to the hundred is 4000

<h3>Estimate the amount of money Yousef will borrow by first rounding to the hundred</h3>

The amount borrowed are given as:

Last term = 1690

This term = 2345

When the amounts are rounded to the nearest hundred, the amounts borrowed become:

Last term = 1700

This term = 2300

The total amount is then calculated as:

Total amount = Last term + This term

Substitute the known values in the above equation

Total amount = 1700 + 2300

Evaluate the sum

Total amount = 4000

Hence, the estimate of the amount of money Yousef will borrow by first rounding to the hundred is 4000
