You need to add a -1

We can find this by setting up the equation like so

x + (-6) + 12 + 15 / 4 = 5

x + 21 = 20

x = 20 -21

x = -1

Now if we insert -1 where x is located in the equation, you will get a means of 5

Max points easy math problem
11Alexandr11 [23.1K]

Solution:

Given:

  • x = -4
  • y = 4

<u>Substitute the values into the equation:</u>

  • x⁶ - x/4y
  • => [(-4)⁶] - (-4)/4(4)

<u>Simplify the numerator and the denominator:</u>

  • => [(-4) x (-4) x (-4) x (-4) x (-4) x (-4)] + 4/16
  • => [(-64) x (-64)] + 4/16
  • => [4096] + 4/16
  • => 4100/16

<u>Simplify the fraction:</u>

  • => 4100/16
  • => 1025 x 4/4 x 4
  • => 1025/4

Correct option is B.
