The distance between the points (x₁,y₁) and (x₂,y₂) is calculated through the equation,
                              d = sqrt ((x₂ - x₁)² + (y₂ - y₁)²)
From our given, we have the point (-3,-1) and (1,y). Substituting these to the equation,
                              5 = sqrt ((-3 - 1)² + (-1 - y)²)
Squaring both sides,
                            25 = (-3 - 1)² + (-1 - y)²

The values of y from the equation are 2 and -4. 

The answers are therefore: (a) <em />(<em>1, 2)</em> and (b) <em>(1, -4)</em>.

Jace owns twice as many dvds an Louis. Bo has sixty fewer dvds than 5 times louis's collection. If jace and bo have the same amo
Yuki888 [10]

Answer: Jace owns 20 dvds

Step-by-step explanation:

Let x represent the number of DVDs that Louis owns.

Jace owns twice as many dvds an Louis. This means that the number of DVDs that Jace owns is 2x.

Bo has sixty fewer dvds than 5 times louis's collection. This means that the number of DVDs that Bo owns is 5x - 60

If jace and bo have the same amount of dvds, it means that

5x - 60 = 2x

5x - 2x = 60

3x = 60

Dividing both sides by 3, it become

x = 60/3

x = 20

I don’t get this someone answer this for me please show all work
Paraphin [41]

Answer:

5x=2x−4−2

Subtract 2 from −4 to get −6.

5x=2x−6

Subtract 2x from both sides.

5x−2x=−6

Combine 5x and −2x to get 3x.

3x=−6

Divide both sides by 3.

x= -6/3

​

 

Divide −6 by 3 to get −2.

x=−2

Which transformations of the graph of f(x) = -4x result in the graph of f(x) = 4x +3?
Furkat [3]

Answer:

Option 1

Step-by-step explanation:

If you flip the sign on the coefficient on x, then it will be a reflection over the x-axis. The + 3 is a trick. Make sure you don't forget that you flip the sign to see the direction you are moving the graph horizontally. In this case, it would be moving to the left, so your 1st option is correct.
