Identify the x-intercept of m(x). <br> m(x)=x^2-2x-8/x^2-x-2

SpyIntel [72]

Answer:

$\large\boxed{x-intercepts:-2\ and\ 4}$

Step-by-step explanation:

$m(x)=\dfrac{x^2-2x-8}{x^2-x-2}\\\\\text{At the beginning we de}\text{fine the domain:}\\\\D:x^2-x-2\neq0\\\\x^2-2x+x-2\neq0\\x(x-2)+1(x-2)\neq0\\(x-2)(x+1)\neq0\iff x-2\neq0\ \wedge\ x+1\neq0\\\boxed{x\neq2\ \wedge\ x\neq-1}\\================================\\\text{The x-intercept is for}\ m(x)=0.\ \text{Therefore we have the equation:}\\\\\dfrac{x^2-2x-8}{x^2-x-2}=0\iff x^2-2x-8=0\\\\x^2+2x-4x-8=0\\x(x+2)-4(x+2)=0\\(x+2)(x-4)=0\iff x+2=0\ \vee\ x-4=0\\\\x=-2\in D\ \vee\ x=4\in D$

Lucy has 20 questions in her science home work

<em><u>Solution:</u></em>

Given that,

Lucy correctly answered 70% of the questions on her science homework

She counted 14 correct answers on her paper

<em><u>To find: Number of questions in her science home work</u></em>

Let "x" be the number of questions in her science home work

From given we can say,

Lucy correctly answered 70% of questions

She counted 14 correct answers

70 % of total questions = 14 correct answers

70 % of x = 14

$70 \% \times x = 14\\\\\frac{70}{100} \times x = 14\\\\0.70x = 14\\\\x = \frac{14}{0.70}\\\\x = 20$

Thus Lucy has 20 questions in her science home work
