Kerri sold her purse for $351. She had originally purchased it for $316. Calculate her profit or loss percentage.​

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

Answer:

Domain (-infinity, infinity) Range (-4, infinity)

Step-by-step explanation:

look at the x axis. the graph is going forever out, so infinity.

now look at the y axis. where does it stop? -4. you might need to use [ instead of ( when answering your problem (that just means including) hope this helps!

Answer:

Step-by-step explanation:

9.

Area = 15 × 5

Area = 75

perimeter = 15 + 6 + 15 + 6 = 42

10.

Area = (10 × 15) ÷ 2 = 75

perimeter = 18 + 10 + 15 = 43

11.

Area = (25 × 10) ÷ 2 = 125

perimeter = 31.6 + 25 + 11.2 = 67.8

Answer:

y- [2] = 4(x - [3])

Answer:

y-2 = 4(x-3)

Step-by-step explanation:

The point slope equation is

y - y1 = m(x-x1) where m is the slope and (x1,y1)

y-2 = 4(x-3)

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

Answer:

Is the other answer correct?

Step-by-step explanation:

35 feet

you can find the answer by looking at the top-most point on the line

this top-most point reaches between 30 and 40 feet, exactly in the middle

therefore it is 35 feet

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.
