Answer:

  • Marty is incorrect.

Step-by-step explanation:

<u>Let's check his work by simplifying the given expression.</u>

  • 2(x - 2) - 2(3)
  • => 2x - 4 - 6
  • => 2x - 10

When I compare Marty's result and this result, they are un-equal. Hence, Marty is incorrect.

<u>Marty's mistake</u>

  • Marty must've got the problem wrong because of not understanding the distributive property.
  • He probably forgot to multiply -2 by 2. Instead, he only subtracted 2 when he should've subtracted 4 from 2x.

The function f is f of x= √4-x
marshall27 [118]

Answer:

  0.5

Step-by-step explanation:

We assume your function is

  f(x)=\sqrt{4-x}

The distance formula can be used to find the distance from the point on the curve (x, f(x)) to the origin:

  d^2 = (x)^2 + (f(x))^2 = x^2 + (4 -x)

Written in vertex form, this is ...

  d^2 = (x -1/2) + 3.75

This has a minimum at x=1/2, so that is the x-coordinate of the point closest to the origin.
