-2x + 6y = 6
y = 2x + 11

Answers

Answer:

(x, y) = (-6, -1)

Step-by-step explanation:

-2x + 6y = 6

y = 2x+11

By substituting the value of y (second equation) into the first equation, we get

-2x + 6(2x+11) = 6

-2x+12x+66 = 6

10x = -60

x = -6

The student Advisory Council here at PC sells red and pink carnations every year for Valentine’s Day. The number of red carnations sold was 1 less than 3 times the number of pink carnations sold. Red carnations were sold for $0.60 each and Pink Carnations sold for $0.80 each. The club made $600.00. How many of each carnation were sold?


Please help!!

Answers

Answer:

The number of :

Red carnations sold = x = 692 carnations

Pink carnations sold = y = 231 carnations

Step-by-step explanation:

Let us represent

The number of :

Red carnations = x

Pink carnations = y

The Student Advisory Council here at PC sells red and pink carnations every year for Valentine's Day.

The number of red carnations sold was 1 less than 3 times the number of pink carnations sold.

x = 3y - 1 .....Equation 1

Red carnations were sold for $0.60 each and Pink Carnations sold for $0.80 each. The club made $600.00. .

$0.60 × x + 0.80 × y = $600

0.6x + 0.80y = 600...... Equation 2

Using substitution method:

Let us substitute, 3y - 1 for x in Equation 2

0.6(3y - 1) + 0.80y = 600

1.8y - 0.6 + 0.80y = 600

1.8y + 0.80y = 600 + 0.6

2.6y = 600.6

y = 600.6 ÷ 2.6

y = 231 carnations

Solving for x

x = 3y - 1 .....Equation 1

x = 3(231) - 1

x =693 − 1

x = 692 carnations

Therefore, The number of :

Red carnations = x = 692 carnations

Pink carnations = y = 231 carnations

What is the image of the point (3,2)(3,2) after a rotation of 90^{\circ}90 ∘ counterclockwise about the origin?

Answers

Answer: = (-2,3)

Step-by-step explanation:

Rotation is a transformation of a figure by rotating it for a specific angle about a fixed point.

Here, fixed point = origin = (0,0)

Transformation rule for rotation of  [tex]90^{\circ}[/tex]counterclockwise about the origin:

[tex](x,y)\to (-y,x)[/tex]

Then, the image of the point (3,2) =  (-2,3)

Hence, the image of the point (3,2) after a rotation of  [tex]90^{\circ}[/tex]counterclockwise about the origin = (-2,3)

The temperature is changing at a constant rate of –0.75ºC per half hour. At 6:45 PM, the temperature was –4.6ºC. At what time was the temperature –2.1ºC? Be sure to include AM or PM in your answer.

Answers

Answer:

5:05 PM

Step-by-step explanation:

Each 30 minutes, we have a change of -0.75

So in an hour , we will have a change of -0.75 * 2 = -1.5

since -2.1 is greater than -4.6, this indicates that it was a time before 6:45 PM

so, let us find the temperature drop

That would be;

-2.1-(-4.6) = -2.1 + 4.6 = 2.5

So let us find the number of half hours

That would be;

2.5/0.75 = 3 1/3 half hours

3 half hours is 90 minutes

1/3 half hour is 1/3 * 30 = 10 minutes

Total number of minutes is;

90 + 10 = 100 minutes

So let us count 100 minutes before 6:45 PM

120 minutes before would be;

4:45 PM

but we want 100 minutes, so we have to add 20 minutes

That would be;

4:45 PM + 20 minutes

= 4:65 which is 5 : 05 PM

Created for the purpose of policing broader frauds against the government, the Secret Service originally focused on counterfeiting. The Secret Service also investigated smugglers, individuals perpetrating land or real-estate fraud, distillers of illegal liquor, and the Ku Klux Klan. In 1894, the protective duties of the Secret Service began informally with agents providing part-time protection to President Grover Cleveland. Following the assassination of President William McKinley, Congress informally requested presidential security service. In 1902, the Secret Service assumed full time responsibility for protecting the president and his family. In 1908, this protection was also extended to the president-elect. In 1913, Congress authorized permanent protection of the president. Following the assassination of President John F. Kennedy, the Secret Service also became responsible for protecting presidential and vice-presidential nominees and candidates, and the widows of presidents.A law enforcement agency can expand its jurisdiction at willThe jurisdiction, or power and scope of an agency, should be precisely defined at the time of the agencys creationThe jurisdiction, or power and scope of an agency, changes to respond to law enforcement needs in new situationsA law enforcement agency will have poorly defined responsibilities if its jurisdiction is not clearly defined from the beginning Select the subject of the sentence.
