Verizon [17]

Answer:

B) −2

Explanation:

When x is positive then y is positive integer.

When x is negative then y is negative integer.

<u>For Option A</u>

  • y = 2(-3) + 5
  • y = -1              [x is negative so is y]

<u>For Option B</u>

  • y = 2(-2) + 5
  • y = 1               [<u>x is negative</u> but <u>y is positive</u>]

<u>For Option C</u>

  • y = 2(1) + 5
  • y = 7               [x is positive so is y]

<u>For Option D</u>

  • y = 2(2) + 5
  • y = 9                [x is positive so is y]

Solve for x.<br> Sqrt8 (Sqrt2 - x) = 11
Alexus [3.1K]

Answer:\frac{-7\sqrt{2} }{4}

Step-by-step explanation:

So first, let's get rid of the parentheses. We can multiply it out to get \sqrt{16}-x\sqrt{8} =11. We know that the square root of 16 is ±4, so now our equation is ±4 - x\sqrt{8}=11. I'm guessing since the problem only has one solution it's most likely only positive 4, so let's revise our equation to 4 - x\sqrt{8}=11. We can use inverse operations to make the a little easier to solve: -7= x\sqrt{8}. We divide both sides by \sqrt{8} to get \frac{-7}{\sqrt{8} } =x, which we can rationalize (remove the square root from the denominator so that it's a proper answer) by multiplying by \frac{\sqrt{8} }{\sqrt{8} } (which is equal to one so we can use it) which is equal to \frac{-7\sqrt{8} }{8}. Let's finish this by simplifying it. \sqrt{8} =2\sqrt{2} (2x2^{2}). We can simplify it further by simplifying the 2, making it \frac{-7\sqrt{2} }{4}.

Hope this wasn't too confusing! I'll answer any questions.
