Which ordered pairs are solutions to the inequality 2x +y > -4? Select each correct answer. (0, 1) (-3,0) (4 – 12) (-1, -1) (5,- 12 )​

Answers

Answer:

(5,-12)

(-3,0)

(-1,-1)

Step-by-step explanation:

For (4, −12): 2(4) - 12 = 8 - 12 = -4                  [false]

For (−3, 0): 2(-3) = -6 < -4                                [false]

For (5, −12): 2(5) - 12 = 10 - 12 = -2 > -4         [true]

For (0, 1): 2(0) + 1 = 1 > -4                              [true]

For (−1, −1): 2(-1) - 1 = -2 - 1 = -3 > -4            [true]

Therefore, (5, -12), (0, 1) and (-1, -1) satisfies the inequality 2x + y > -4

For (7, 12): 12 - 2(7) = 12 - 14 = -2 > -3                   [false]

For (0, −2): -2 - 2(0) = -2 > -3                                   [false]

For (5, −3): -3 - 2(5) = -3 - 10 = -13 < -3                   [true]

For (−6, −3): -3 - 2(-6) = -3 + 12 = 9 > -3                  [false]

For (1, −1): -1 - 2(1) = -1 - 2 = -3                              [true]

Therefore, (5, -3) and (1, -1) satisfy the inequality y - 2x ≤ -3

The situation is represented by 2.25x + 2.65y ≥ 8

The pyramid of Khafre measured 143.5 meters high. The pyramid of Menkaure measured 65.5 meters high. Write and solve an equation to find d, the difference in the heights of these two pyramid.

Answers

Answer:

See below

Step-by-step explanation:

The pyramid of Khafre measured 143.5 meters high.The pyramid of Menkaure measured 65.5 meters high.

The difference in the heights of the two pyramids:

d = 143.5 m - 65.5 md = 78 m

Lets see

d is difference between the heights

143.565.5

So

d=143.5-65.5d=78m

draw an ordered stem and leaf diagram to show infomation 245

Answers

Answer:

if asked to find stem leaf 245 scale key then 2 | 45 is what we could show to one side of the diagram.

We then use organise all numbers in numerical order lowest to highest in a horizontal list to copy.

Then draw a vertical line for your stem hopefully it is on lined paper.

single digits 1-9 go right side.

tenths get split keeping digits rights side

hundred units get split keeping tenth and single digits right side

and so forth so that nly the first number of larger numbers is on the left, just first digit. Being the first digit of numbers higher than 9.

Larger numbers that have 3 digits are more than double digits I've called 100th units

Numbers lower than 9 will be on rights side on the first line.

1-9  =  0 | 1  2 3 4 5 6 7 8 9

10-19   1 | 0 1 2 3 4 5 6 7 8 9

20-29  2| 0 1 2 3 4 5 6 7 8 9

100-110 = 1 | 00 01 02 03 etc.. becomes our first 100th line

We use thsi by counting how many numbers we have before drawing and by writing the scale key ie) 1|1 if 11 is shown etc. sometimes just called key.

what is [tex]−3.64⋅|5.3|−1.5^3[/tex]

Answers

Answer:

- 22.667

Step-by-step explanation:

1.5^3 = 1.5 x 1.5 x 1.5 = 3.375

- 3.64 ⋅ | 5.3 | - 1.5^3

= ( - 3.64 ⋅ | 5.3 | ) - 1.5^3

= ( - 3.64 ⋅ 5.3 ) - 1.5^3

= ( - 3.64 x 5.3 ) - 1.5^3

= - 19.292 - 3.375

= - 22.667
