8 - 4m - 20 = 3m - 27 

- 4m - 12 = 3m - 27
+4m          +4m

        - 12 = 7m - 27
        +27          + 27
 
         15 = 7m

m = 15/7

1. subtract 4 from 8;
4(m+5)=3(m-9)

2. distribute:
4m+20=3m-27

3. subtract 20 to both sides:
4m=3m-47

4. subtract 3m from both sides:
m=-47

Find the rational roots f(x) =3x3+ 2x2 + 3x + 6
Ann [662]

The rational roots of f(x) = 3x^3 + 2x^2 + 3x + 6 are ±(1, 2, 3, 6, 1/3, 2/3)

<h3>How to determine the rational root of the function f(x)?</h3>

The function is given as:

f(x) = 3x^3 + 2x^2 + 3x + 6

For a function P(x) such that

P(x) = ax^n +...... + b

The rational roots of the function p(x) are

Rational roots = ± Possible factors of b/Possible factors of a

In the function f(x), we have:

a = 3

b = 6

The factors of 3 and 6 are

a = 1 and 3

b = 1, 2, 3 and 6

So, we have:

Rational roots = ±(1, 2, 3, 6)/(1, 3)

Split the expression

Rational roots = ±(1, 2, 3, 6)/1 and ±(1, 2, 3, 6)/3

Evaluate the quotient

Rational roots = ±(1, 2, 3, 6, 1/3, 2/3, 1, 2)

Remove the repetition

Rational roots = ±(1, 2, 3, 6, 1/3, 2/3)

Hence, the rational roots of f(x) = 3x^3 + 2x^2 + 3x + 6 are ±(1, 2, 3, 6, 1/3, 2/3)

The complete parameters are:

The function is given as:

f(x) = 3x^3 + 2x^2 + 3x + 6

The rational roots of f(x) = 3x^3 + 2x^2 + 3x + 6 are ±(1, 2, 3, 6, 1/3, 2/3)

If T equals 1 / r + 1 / s equals r + S over RS, then what is 1 / T in terms of R&amp;S?
Thepotemich [5.8K]
T=\dfrac{1}{r}+\dfrac{1}{s}\\\\T=\dfrac{1\cdot s}{r\cdor s}+\dfrac{1\cdot r}{r\cdot s}\\\\T=\dfrac{s}{rs}+\dfrac{r}{rs}\\\\T=\dfrac{s+r}{rs}\to\dfrac{1}{T}=\dfrac{rs}{s+r}

You are running a fuel economy study. One of the cars you find is blue. can travel 35 1/2 miles on 1 1/4 gallons of gasoline. An
IgorLugansk [536]

Answer:

1) 28.4 miles per gallon

2) 34 miles per gallon

3) the red car

Step-by-step explanation:

We have the following information:

  • <em>Blue car:</em>

<em>Travels 35 1/2 miles on 1 1/4 gallons of gasoline</em>

  • <em>Red car:</em>

<em>Travels 27 1/5 miles on 4/5 gallons of gasoline</em>

<em />

We want to know the unit rate for miles per hour, and to do it we have to divide the miles they travel by the gallons each car uses:

  • Blue car:

(35 1/2) / (1 1/4) = 28.4 miles per gallon

  • Red car:

(27 1/5) / (4/5) = 34 miles per gallon

The red car travels greater distance with 1 gallon of gasoline
