if trangle pqr is translated 4 units to the right to form triangle p'q'r' how are the values on the orderd pairs affected by the
Vesna [10]

Answer:

The x-coordinate of each point will increase by 4.

Step-by-step explanation:

So Triangle PQR is being translated 4 units to the <em>right</em>. Since we are going to the <em>right</em>, this is a shift on the x-coordinate.

And since we're going 4 units, every x-coordinate is going to be added by 4.

In other words, if we have:

A(x,y)

Then the new coordinate, A', is:

A(x,y)\rightarrow A' (x+4,y)

So, let's find the new coordinates of each point.

Point P is (-5,6). So:

P(-5,6)\rightarrow P'(-5+4,6)=P'(-1,6)

The new Point P is at (-1,6).

Point Q is at (2,6). So:

Q(2,6)\rightarrow Q'(2+4,6)=Q'(6,6)

The new Point Q would be at (6,6).

And Point R is at (-3,2). So:

R(-3,2)\rightarrow R(-3+4,2)=R(1,2)

The new Point R is at (1,2).

And we're done!

Jessica, Chau, and Kareem sent a total of 84 text messages during the weekend. Kareem sent 4 times as many messages as Chau. Jes
swat32

Answer:

Number of messages sent by Chau = 15

Number of messages sent by Kareem = 4 * 15 = 60

Number of messages sent by Jessica = 15 - 6 = 9

Step-by-step explanation:

Let number of messages sent by Chau = c

Number of messages sent by Kareem = 4 times as Chau

                                                                = 4 * c = 4c

Number of messages sent by Jessica = 6 fewer messages than Chau

                                                               = c - 6

Total messages = 84

<u>c + 4c + c</u> - 6 = 84                {Combine like terms}

<u>6c</u> - 6 = 84         {Add 6 to both sides}

6c  = 84 + 6

6c = 90   {Divide both sides by 6}

c = 90/6

c = 15

Number of messages sent by Chau = 15

Number of messages sent by Kareem = 4 * 15 = 60

Number of messages sent by Jessica = 15 - 6 = 9
