Answer:

C

Step-by-step explanation:

For example A you would divide 180?3 and thats

your constant rate of change. For C 200 divided by 4 = 50 so 50s your constant rate of change! Please amrk me brainliest and i hope this helped!!!!!

2. Determine the sum of the first 400 ODD numbers.<br><br>​
il63 [147K]

Odd numbers take the form 2n-1, where n\ge1 is an integer. When n=400, the last odd number would be 799. So we're adding

S=1+3+5+\cdots+795+797+799

By reversing the order of terms, we have

S=799+797+795+\cdots+5+3+1

and we can pair up terms in both sums at the same position to write

2S=(1+799)+(3+797)+(5+795)+\cdots(795+5)+(797+3)+(799+1)

so that we are basically adding 400 copies of 800, and from there we can find the value of the sum right away:

2S=400\cdot800\implies S=160,000

###

We could also make use of the formulas,

\displaystyle\sum_{i=1}^n1=n

\displaystyle\sum_{i=1}^ni=\dfrac{n(n+1)}2

We have

S=\displaystyle\sum_{i=1}^{400}(2i-1)=2\sum_{i=1}^{400}i-\sum_{i=1}^{400}1=400(400+1)-400=400^2=160,000

Which graph shows the solution to this system of inequalities?<br> y &lt; 2x + 4<br> y &gt; -X -3
Arturiano [62]

Answer:

The answer is Graph X.

  • Always start by isolating the variable \color{red}y on the left side of the inequality.
  • Change the inequality to equality symbol.
  • Graph the boundary line from step 2 in the XY-plane.
  • The last step is to shade one side or region of the boundary line.
