Answer:

see explanation

Step-by-step explanation:

Calculate the length using the distance formula

AB = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = A(4,3) and (x₂, y₂ ) = B(- 2, 1)

AB = \sqrt{(-2-4)^2+(1-3)^2}

     = \sqrt{(-6)^2+(-2)^2}

     = \sqrt{36+4}

     = \sqrt{40}

     = \sqrt{4(10)} = \sqrt{4} × \sqrt{10} = 2\sqrt{10} ← exact length

Solve the inequality −x/2<4
FinnZ [79.3K]

Isolate the x. First, multiply 2 to both sides

-x/2(2) < 4(2)

-x < 4(2)

-x < 8

Isolate the x. Divide - 1 to both sides (because you are dividing a negative number, flip the sign).

-x/ -1 < 8/-1

x > -8 is your answer

hope this helps
