Find the measures of m and n.

Mathematics
1 answer:
hodyreva [135]3 years ago
6 0

Answer:

m = 4

n = 5

Step-by-step explanation:

m + 8 = 3m\\\\m - 3m = - 8\\\\-2m = - 8\\\\m = 4

2n - 1 = 9 \\\\2n = 9 + 1\\\\2n = 10\\\\n = 5

1. Rational numbers can be written as a ratio (fraction)
Whole numbers are rational. 5 = 5/1, for example.
Square roots are NOT rational.  Example: √3
However, square roots of square numbers can be simplified, and are therefore rational. <span>√4 = 2, rational.</span>

√4 + <span>√16 = 2 + 4 = 6. rational
</span>√5 + √36...<span> irrational
</span>√9 + <span>√24... irrational
</span>2 × <span>√4 = 2 × 2 = 4. rational
</span>√49 × <span>√81 = 7 × 9 = 63. rational
</span>3√12... irrational

2. n^\frac12=\sqrtn
9^\frac32=9^3\times\frac12=\sqrt{9^3}=\sqrt{729}=29

3. \frac{n^a}{n^b}=n^{a-b}

\frac{a^\frac13}{a^\frac14}=a^{\frac13-\frac14}=a^{\frac{1}{12}}

4. n^\frac1x=\sqrt[x]n

\sqrt[3]{m^2n^5}=m^{\frac23}n^{\frac53}

5. \sqrt{a}\times\sqrt{b}=\sqrt{ab}

\sqrt{3}\times\sqrt{12}=\sqrt{3\times12}=\sqrt{36}=6

A, since neither 3 nor 12 is a square but we end up with 6.

The function g is defined by:
Alisiya [41]

<em>g(x)</em> = <em>x</em>² - <em>x</em> - 6

so

<em>g</em> (-4) = (-4)² - (-4) - 6 = 16 + 4 - 6 = 14

When <em>g(x)</em> = 6, we have

6 = <em>x</em>² - <em>x</em> - 6

<em>x</em>² - <em>x</em> - 12 = 0

Solve for <em>x</em>. We factorize this easily as

(<em>x</em> - 4) (<em>x</em> + 3) = 0

which gives

<em>x</em> - 4 = 0   <u>or</u>   <em>x</em> + 3 = 0

<em>x</em> = 4   <u>or</u>   <em>x</em> = -3

Yes it is a function!, all the first numbers are none repeating, for example it says -5,4,6 since they are not the same this is a function
