To find the relative frequency, we have to first divide 300 by 500 and on doing so we will get 0.6 .

And then to find the percentage, we need to multiply it with 100 . And 0.6 times 100 = 60%.

So out of the given 4 options, correct option is the last option .

Which zero pair could be added to the function f(x)=x^2+12x+6 so that the function can be written in vertex form?
andrew11 [14]
<span>f(x) = x</span>² <span>+ 12x + 6  </span>→ y = x² + 12x + 6<span>

Let us convert the standard form into vertex form.

1) Complete the squares. Isolate x</span>² and x terms.
<span>y - 6 = x</span>² + 12x
<span>
2) Create the perfect square trinomial. Whatever number is added on one side must also be added on the other side. 

y - 6 + 36 = x</span>² + 12x + 36<span>
y + 30 = (x + 6)</span>²
<span>y = (x + 6)</span>² - 30  ← Vertex form
<span>
To check:

y = (x + 6) (x + 6) - 30
y = x</span>² + 6x + 6x + 36 - 30
<span>y = x</span>² + 12x + 6<span>

The zero that could be added to the given function is 36, -36</span>

Answer:

Concept: Mathematical Derivation

  1. We are given x^2 +6x+2x+12
  2. Hence we simplify: x^2 + 8x +12
  3. Now we factor: (x+2)(x+6)
  4. By mathematical logic we now proved that the roots are x=-2 and x=-6

What is the answer to. 4x + 7&lt;8
sukhopar [10]
First, subtract 7 on both sides. Now, you have 4x<1. Divide by 4 on both sides. Finally, you get x<1/4 (a quarter or said as one-fourth). So, x<1/4.
