You are told that the average rate of change of a particular function is always negative. What can you conclude about the graph
ira [324]
A negative average rate of change means that as x increases, y decreases. That means that the graph goes down to the right.

PLEASE HELP 45 POINTS!!!!!
Nady [450]

Answer:

  • \sf x = 5
  • \sf DF = 12

setting up proportionality equation:

\sf \dfrac{big-side}{big-diagonal}   = \sf \dfrac{small-side}{small-diagonal}

\sf \hookrightarrow \dfrac{7}{16+x+7}  = \dfrac{4}{16}

\sf \hookrightarrow  \dfrac{7}{23+x}  = \dfrac{4}{16}

\sf \hookrightarrow 4(23+x) = 112

\sf \hookrightarrow 92 + 4x = 112

\sf \hookrightarrow 4x = 112- 92

\sf \hookrightarrow 4x = 20

\sf \hookrightarrow x = 5

<u>Find DF:</u>

\hookrightarrow \sf x + 7

\hookrightarrow \sf  5 + 7

\hookrightarrow \sf 12

The sum of five consecutive positive integers is 2020. Find the largets of these numbers.
Alona [7]

Answer:

406

Step-by-step explanation:

let the 5 consecutive positive integers be

n , n + 1 , n + 2 , n + 3 , n + 4 , then

n + n + 1 + n + 2 + n + 3 + n + 4 = 2020

5n + 10 = 2020 ( subtract 10 from both sides )

5n = 2010 ( divide both sides by 5 )

n = 402

then

largest integer = n + 4 = 402 + 4 = 406
