Well, the idea is to "rationalize the denominator", which is another way to say "getting rid of that pesky radical in the bottom".

so, we'll do so by multiplying for "something" that raises the radicand and then it comes out

\bf \cfrac{8}{8\sqrt{3}}\implies \cfrac{1}{\sqrt{3}}\implies \stackrel{rationalizing~it}{\cfrac{1}{\sqrt{3}}\cdot \cfrac{\sqrt{3}}{\sqrt{3}}}\implies \cfrac{1\sqrt{3}}{(\sqrt{3})^2}\implies \cfrac{\sqrt{3}}{3}

bear in mind that   \bf \cfrac{something}{something}=1\qquad \qquad \cfrac{same}{same}=1\qquad \qquad \cfrac{\sqrt{3}}{\sqrt{3}}=1

so, all we really did was, multiply it by "1", and recall that anything times 1 is just itself, so the fraction never really changed in value, just looks different, is all.

Translate this phrase into an algebraic expression.
Naily [24]

Answer:

2m + 8

Step-by-step explanation:

It's rather simple to break it down, take "8 more" as (+ 8) and twice Matt's savings into (2 * m) which then becomes simply (2m). Because of pemdas, your final answer should be 2m first then + 8, so 2m+8

12. Algebra Two similar figures are similar based on
algol [13]

Answer:

  • a = ± 2

Step-by-step explanation:

Let the scale factor is k.

<u>Then the transformation is:</u>

  • (x, y) → (kx, ky)

<u>We have:</u>

  • (x, y) → (12x, 3a²y)

<u>The scale factor is k = 12, find the value of a:</u>

  • 3a² = 12
  • a² = 4
  • a = √4
  • a = ± 2

I can’t figure out what it is asking. How do you find where each line crosses the y-axis?..
EleoNora [17]
They want you to find the y intercept. This is the point where the curve or line crosses the y axis. To find the y intercept, plug in x = 0

y = 3x+4
y = 3*x + 4
y = 3*0 + 4 ... notice x has been replaced with 0
y = 0 + 4
y = 4

So when x = 0, the value of y is y = 4. This means the y intercept is located at the point (0,4). This is all for problem 1. Problem 2 is handled much the same way.
