Graph the numbers that are solutions to both inequalities.

nadya68 [22]

Answer:

p ∈ [5 , 6)

Step-by-step explanation:

p + 6 ≥ 11

⇒ p ≥ 11 - 6

⇒ p ≥ 5

⇒ p ∈ [5 , +∞)

3p < 18

⇒ p < 18/3

⇒ p < 6

⇒ p ∈ (-∞ , 6)

Then

p the solution to both equations verify:

p ∈ (-∞ , 6) ∩ [5 , +∞)

Conclusion :

p ∈ [5 , 6)

A new neighborhood activity complex is being built in erie. The perimeter of the rectangular playing field is 256 yards. The len

maw [93]

Answer:

The length of the rectangular playing field is 84 yards and the width is 44 yards

Step-by-step explanation:

Let

x ------> the length of the rectangular playing field

y -----> the width of the rectangular playing field

we know that

The perimeter of the rectangular playing field is equal to

$P=2(x+y)$

$P=256\ yd$

$256=2(x+y)$ ------> equation A

we have that

$x=2y-4$ -----> equation B

Solve the system by substitution

Substitute equation B in equation A and solve for y

$256=2(2y-4+y)$

$128=3y-4$

$3y=128+4$

$3y=132$

$y=44$

Find the value of x

$x=2(44)-4=84$

therefore

The length of the rectangular playing field is 84 yards and the width is 44 yards

You have a poster that is 5 feet by 3 feet. You want to put a frame, with a uniform width, around the picture. The poster and th

Semenov [28]

Please don't give me credit, but I want to say that;

1. You need a picture attached to this

2. Make sure you add if 5 feet is the length or width, in addition to the 3 feet

3. The width can't be a negative value, so eliminate the negative answers

4. For the second answer, why is there a coma preceding another value? The width can can only be one value

You can add all these elements

Hoped this helped!

Use the recursive relationship to complete the next two rows of Pascal's triangle. Row 5: 1 _ _ _ _ 1 Row 6: 1 _ _ _ _ _ 1

frosja888 [35]

Answer:

1 5 10 10 5 1 Row 5

1 6 15 20 15 6 1 Row 6

Recursive relationship:

Each row has number of positions = row number + 1. The Row 0 is always 1.

The first and last number in each row is 1, the number in the second position and the penultimate corresponds to the number of the row. The middle numbers correspond to the sum of the two numbers in the top row. The resulting number from the addition is located in the middle of the numbers added in the next row.

Step-by-step explanation:

The pascal's triangle

* Row 0 = 1

* Row 1 = 1 1

1 Row 0

1 1 Row 1

Since there are only two positions, the first and last are 1.

*Row 2 = 1 _ 1

1 Row 0

1 1 Row 1

1 2 1 Row 2

2 is the sum of 1 + 1 and we place it in the next row between the added numbers 1 and 1.

* Row 3 = 1 _ _ 1

1 Row 0

1 1 Row 1

1 2 1 Row 2

1 3 3 1 Row 3

1 + 2 = 3 (the row number and the and adding the numbers from the previous row)

* Row 4 = 1 _ _ _ 1

1 Row 0

1 1 Row 1

1 2 1 Row 2

1 3 3 1 Row 3

1 4 6 4 1 Row 4

1 + 3 = 4 (the row number)

3 +3 = 6

* Row 5 = 1 _ _ _ _ 1

1 Row 0

1 1 Row 1

1 2 1 Row 2

1 3 3 1 Row 3

1 4 6 4 1 Row 4

1 5 10 10 5 1 Row 5

1 + 4 = 5

4 + 6 = 10

* Row 6 = 1 _ _ _ _ _ 1

1 Row 0

1 1 Row 1

1 2 1 Row 2

1 3 3 1 Row 3

1 4 6 4 1 Row 4

1 5 10 10 5 1 Row 5

1 6 15 20 15 6 1 Row 6

1 + 5 = 6

5 + 10 = 15

10 + 10 = 20
