The point A(-2, 3) is translated using T: (x,y) → (x + 4, y + 2). What is the distance from A to A'? 2 5 2

stepan [7]

For this case, we have that by definition, the distance between two points is given by:

$d = \sqrt {(x_ {2} -x_ {1}) ^ 2+ (y_ {2} -y_ {1}) ^ 2}$

We have to:

$A: (x_ {1}, y_ {1}) = (- 2,3)\\A ':( x_ {2}, y_ {2}) = (x + 4, y + 2) = (- 2 + 4, 3 + 2) = (2,5)$

Substituting:

$d = \sqrt {(2 - (- 2)) ^ 2+ (5-3) ^ 2}\\d = \sqrt {(4) ^ 2 + (2) ^ 2}\\d = \sqrt {16 + 4}\\d = \sqrt {20}$

Answer:

$d = \sqrt {20}$

Start by finding the first number on the Y axis,

then find the next number on the x axis, you can move up OR down if you have to

Make sure if your number is a - for instance, (-5, 1) you plot it on the negative 5 one, not the positive five.

Given that 2x + 7 equals 27 and 3x + 1 equals 28 does 2x + 7 equals 3 x + 1

ICE Princess25 [194]

2×+7=27
2×-7=27-7
2× =20
2/× =20/2
× = 10
2(10)+7=27

3×+1=28
3×-1=28-1=27
3× =27
3/× =27/3
× =9
3(9)+1=28

27 does not equal 28
so no
