What is the imgae point of (-2,-3) after a translation right 2 units and 4 up units?​
kherson [118]

the image point of (-2,-3) after a translation right 2 units and 4 up units is (0,1) .

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

Here we have , to find  the image point of (-2,-3) after a translation right 2 units and 4 up units . Let's find out:

Initially we have the point as  (-2,-3) , Following transformations are done :

a translation right 2 units :

The point is (-2,-3)  , let (x,y)=(-2,-3) . Translation is 2 units right , means there is change in x coordinate by +2 , i.e.

⇒ (x,y)=(-2,-3)

⇒ (x+2,y)=(-2+2,-3)

⇒ (x+2,y)=(0,-3)

a translation  4 up units:

The point is (0,-3)  , let (x,y)=(0,-3) . Translation is 4 units up , means there is change in y coordinate by +4 , i.e.

⇒ (x,y)=(0,-3)

⇒ (x,y+4)=(0,-3+4)

⇒ (x,y+4)=(0,1)

Therefore , the image point of (-2,-3) after a translation right 2 units and 4 up units is (0,1) .

September 6 is a Read Book Day.Polina read 5 times as many pages as Marcus read.Together,the read 108 pages.How many pages did e
Gemiola [76]

Answer:

The number of pages that Polina read was 90 and the number of pages that Marcus read was 18

Step-by-step explanation:

Let

x -----> number of pages that Polina read

y ----> number of pages that Marcus read

we know that

x+y=108 ----> equation A

x=5y -----> equation B

substitute equation B in equation A and solve for y

5y+y=108\\6y=108\\y=18

Find the value of x

x=5y -----> x=5(18)=90

therefore

The number of pages that Polina read was 90 and the number of pages that Marcus read was 18

Answer:

r = -4

Step-by-step explanation:

If M is the midpoint of DE, that would mean that the distance from M to D and M to E would be the same.

This creates the equation 1-8r=13-5r.

Now it's just simple algebra.

You add 8r to both sides, creating 1=13+3r. Then, you subtract 13 from both sides, getting 3r=-12. Dividing both sides by 3 and solving for r, you get r=-4.

Checking our answer, you see that 1-8(-4)=1-(-32)=1+32=33, and 13-5(-4)=13-(-20)=13+20=33.
