Find all values of a such that (a-3)/sqrta=-sqrta

Mariana [72]

Answer:

From the Pythagorean theorem...

[ distance between (a, 7) and (2, 1) ]2 = [a - 2]2 + [7 - 1]2

And they tell us that the distance equals 3√5 , so

[ 3√5 ]2 = [a - 2]2 + [7 - 1]2

45 = [a - 2]2 + 36

9 = [a - 2]2

±√9 = a - 2

± 3 = a - 2

± 3 + 2 = a

a = 3 + 2 = 5 or a = -3 + 2 = -1

and

5 + -1 = 4

Step-by-step explanation:
