Yes; two domain values exist for range value –2.

No; the relation passes the vertical line test.

Yes; only one range value exists for each domain value.

Answers

Answer 1

Answer:

yes; only one range value exists for each domain value.

Step-by-step explanation:

The x value don't repeat. Which is: -3, -1, 1, 5.

Answer 2

Answer:

yes, the given relation is a function.

Step-by-step explanation:

The given relation is

{(–3, –2), (–1, 0), (1, 0), (5, –2)}

A relation is called function if each element of the domain is paired with exactly one element of the range.

It means for each value of x there exist a unique value of y.

In the given relation for each value of x there exist a unique value of y.

Therefore the required solution is yes and this relation is a function.

Step-by-step explanation:

letter d

because there is no repeating x's

Answers

137 because they are 180 angles so you subtract 180-43=137.

Answer:

so in this figure the 43°=y°(by vertical opposite angle)

y°+z°=180°(by linear pair)

43°+z°=180°

z=180°-43°

z=137°

The concession stand sells hot dogs and soda during the pee-wee football games.John bought 6 hot dogs and 4 sodas and paid $6.70. Jessica bought 4 hot dogs and 3 sodas and paid $4.65. At what prices are the hot dogs and sodas sold? Show your work.

Answers

Answer: Hotdog cost $0.75

Price of soda = $0.55

Step-by-step explanation:

Let the price of hot dogs be x.

Let the price of sodas be y.

6x + 4y = 6.70 ...... i

4x + 3y = 4.65 ....... ii

Multiply equation i by 4

Multiply equation ii by 6

24x + 16y = 26.80 ........ iii

24x + 18y = 27.90 ......... iv

Subtract iii from iv

2y = 1.10

y = 1.10/2

y = $0.55

Price of soda = $0.55

From equation i,

6x + 4y = 6.70

6x + 4(0.55) = 6.70

6x + 2.20 = 6.70

6x = 6.70 - 2.20

6x = 4.50

x = 4.50/6

x = $0.75

Hotdog cost $0.75

Jane drew a point that was 3 units to the right of the y-axis and 5 units above x-axis what ordered pair for this location

Answers

Answer:

(3,5)

Step-by-step explanation:

If you imagine a grid in your head, moving 3 units to the right is the same as 3 on the x axis, and 5 units above the x axis is the same as 5 on the y axis. X goes before y in an ordered pair, so the answer would be (3,5). Hope this helps!!

A is the poin 3,5 and b is the point 0,k if the distance of ab is 5 units find the possible value of k

Answers

Answer:

K is either 9 or 1

Step-by-step explanation:

Sqrt((0 - 3)² + (k - 5)²) = 5

Square both sides

(0 - 3)² + (k - 5)² = 5²

(0 - 3)² + (k - 5)² = 25

-3² + (k - 5)² = 25

9 + (k-5)(k-5) = 25

9 + k² - 5k - 5k + 25 - 25 = 0

k² - 10k +9 = 0

k² - 9k - k + 9 = 0

k(k - 9) - 1(k - 9) = 0

k - 1 = 0 ; k = 1

k - 9 = 9; k = 1

K = 9 or k = 1

K is either 9 or 1

What is congruence?

If two figures are exactly the same in sense of their length side all things then they will be congruent.

In other meaning, if you can copy a figure then that copy and the original figure will be congruent.

As per the given △NKW.

m∠K = m∠Z

Side KW = side ZE

m∠W = m∠E

Thus, by angle side angle theorem both triangles will be congruent.

Hence "ΔUZE ≅ △NKW ​by angle side angle postulate of congruency".
