Write a quadratic equation in standard form that has the following solutions: x = 4/3 and x = - 2/5
Leni [432]

Answer:

15x^2 - 14x - 8 = 0.

Step-by-step explanation:

(x  - 4/3)(x + 2/5) = 0

Converted to integer values by multiplying the first bracket by 3 and the second by 5:

(3x - 4)(5x + 2) = 0

Expanding the brackets:

15x^2 + 6x - 20x - 8 = 0

15x^2 - 14x - 8 = 0.

Chris jogged 1 3 of a mile to his friends house in 1 12 of an hour. Compute the unit rate from the complex fraction 1 3 1 12 mil
olga2289 [7]

The unit rate from the complex fraction ¹/₃ ÷ ¹/₁₂ is 4 miles per hour

<h3>Further explanation</h3>

Order of Operations in Mathematics follow this following rule :

  1. Parentheses
  2. Exponents
  3. Multiplication and Division
  4. Addition and Subtraction

This rule is known as the PEMDAS method.

In working on a mathematical problem, we first calculate operation that is in parentheses, follow by exponentiation, then multiplication or division, and finally addition or subtraction.

<em>Let us tackle the problem!</em>

\texttt{ }

<em>We will calculate the fraction by using this following formula:</em>

\texttt{Speed of Chris} = \texttt{Distance} \div \texttt{Time Taken}

\texttt{Speed of Chris} = \frac{1}{3} \texttt{ miles} \div \frac{1}{12}\texttt{ hour}

\texttt{Speed of Chris} = (\frac{1}{3} \times \frac{12}{1}) \texttt{ miles per hour}

\texttt{Speed of Chris} = (\frac{12}{3}) \texttt{ miles per hour}

\texttt{Speed of Chris} = 4 \texttt{ miles per hour}

\texttt{ }

<h2>Conclusion:</h2>

The unit rate from the complex fraction ¹/₃ ÷ ¹/₁₂ is 4 miles per hour
