What is the average rate of change of the function below on the interval from x = 0 to x = 2?
Salsk061 [2.6K]
Average rate of change = \frac{change-of-y}{change-of-x} =  \frac{f(x_2)-f(x_1)}{x_2-x_1}

\frac{f(2)-f(0)}{2-0} = \frac{250-0}{2-0}

I need an essay about the American dream
MariettaO [177]

I can get you a little bit :P

Most people, if not all in the US always want to live the American dream at some point in their lives. But the question is, what is the meaning of the American dream, and how can people achieve this vague and elusive realisation? The American dream is a national philosophy or a belief that specifies the ideal factors such as democracy, freedom, rights and equality that accords every citizen equal opportunity to prosper and achieve their set goals (Glenn, 2002). The foundation of the American dream is deeply rooted in the declaration of independence that assert that “all men are created equal”. In simple terms, the American dream eliminates the artificial barriers to prosperity and promotes upward social mobility for every individual in the US depending on their hard work irrespective of their, social, religious, historical and racial background. The American dream is a slogan that is selling across the globe and up to date we see millions of people crossing the American borders as immigrants in search of this dream that cannot otherwise be achieved in their homelands. The American dream is a reality as we see it through how different people in the US have developed and better their own ingenuity and achieve their goals through their best efforts. Making this dream a reality is not a straight path as it is all about overcoming the challenges which at the end of the day differentiates a resilient individual from the rest.

  • Left to Right

<u>Algebra I</u>

  • Equality Properties
  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

<u>Step 1: Define Systems</u>

y = x - 4

y = 4x + 2

<u>Step 2: Solve for </u><em><u>x</u></em>

<em>Substitution</em>

  1. Substitute in <em>y</em>:                    x - 4 = 4x + 2
  2. Isolate <em>x </em>terms:                   -4 = 4x + 2
  3. Isolate <em>x</em> term:                     -6 = 4x
  4. Isolate <em>x</em>:                              -3/2 = x
  5. Rewrite:                               x = -3/2

<u>Step 3: Solve for </u><em><u>y</u></em>

  1. Define equation:                    y = x - 4
  2. Substitute in <em>x</em>:                       y = -3/2 - 4
  3. Subtract:                                 y = -11/2

Question 3 of 28
Assoli18 [71]

Answer:

Option C. √280

Step-by-step explanation:

From the question given above, the following data were obtained

MN = 19

ML = 9

LN =?

We can obtain the value of LN by using the pythagoras theory as illustrated:

M ² = ML² + LN²

19² = 9² + LN²

361 = 81 + LN²

Collect like terms

361 – 81 = LN²

280 = LN²

Take the square root of both side

LN = √280

Therefore, the length of LN is √280
