Answer:

The answer to your question is: x = 3

Step-by-step explanation:

Point (3, -1)

Perpendicular

x = 3

Because the given line cuts the y-axis then the new line must cut the x-axis, and also because the point given says that x = 3.

A hairdresser is deciding where to open her own studio. If the hairdresser chooses Location A, she will pay $1200 per month in r
Ymorist [56]
She will need to cut 26.6 haircuts a month a location A to break even (1200/45 = 26.6) so roughly 27 haircuts to make a profit


She will need to cut 30 haircuts at location B to break even (1800/60 = 30) and 31 hair cuts to see a profit.


She will need to cut 30.67 haircuts at location A and 33 haircuts at location B to make the same profit at either location (Roughly $180).


30.67 x 45 = 1380.15 - 1200 = 180

33 x 60 = 1980 - 1800 = 180

<h2>Intersection and Union of Sets</h2><h3>Answer:</h3>

A \cup B = \{ a, b, c, d, e \}

B \cap C = \{ d, e \}

A \cup C = \{ a, b, c, d, e, f \}

<h3>Step-by-step explanation:</h3>

Given:

A = \{ a, b, c, d \}

B = \{ b, d, e \}

C = \{ d, e, f \}

The Union (\cup) of sets A and B is just a set containing all the elements of sets A and B. However, elements that are present in both sets should not repeat in the Union of Sets as the elements of a set should distinct be from each other.

Part i:

A \cup B \\ \{ a, b, c, d \} \cup \{ b, d, e \} \\ \{ a, b, c, d, e \}

The Intersection (\cap) of sets A and B is just a set containing all the elements that are both present in sets A and B.

Part ii:

B \cap C \\ \{ b, d, e \} \cap \{ d, e, f \} \\ \{ d, e \}

Part iii:

A \cup C \\ \{ a, b, c, d, \} \cup \{d, e, f \} \\ \{ a, b, c, d, e, f \}

What value of x is in the solution set of –5x – 15 &gt; 10 + 20x? –2 –1 0 1
stealth61 [152]

Answer:

-2

Step-by-step explanation:

5x – 15 > 10 + 20x

Subtract 5x from each side

5x – 15-5x > 10 + 20x-5x

-15 > 10+15x

Subtract 10 from each side

-15-10 >15x

-25 > 15x

Divide each side by 15

-25/15 > x

-5/3 > x

X must be less than -1  2/3

The only value that is less than -1 2/3 is -2

finlep [7]

Answer: the weight in kilograms is 9.76kg

1 meter of length of rope = 800 g

12.2 meters of the rope= (12.2meters x 800g)/ 1 meter=9760grams

We know that 1000 g = 1kg

 9760 grams = 9760/1000=9.76 kilograms
