LenKa [72]

Answer:

y=1x+8

Step-by-step explanation:

  1. The best way to remember the formula is y=mx+b aka (your mom's ex bf)
  2. Just by looking at the slope you can automatically tell it's moving by one so in your formula, 'm' is the slope.
  3. Add 1x to replace 'm' or you can leave x alone because x is already one, your choice.
  4. b is the indication on where your slope started in the y-axis.
  5. In this case, by looking at the y-axis on the graph, the slope starts at 8 so that will be your b.
  6. Therefore, your answer is y=1x+8

Find the sum of 46 + 42 + 38 + ... + (-446) + (-450)46+42+38+...+(−446)+(−450)
JulijaS [17]

sum of sequence Find the sum of 46 + 42 + 38 + ... + (-446) + (-450) is -25,250

<u>Step-by-step explanation:</u>

We need to find sum of sequence  : 46 + 42 + 38 + ... + (-446) + (-450)

Given sequence is an AP with following parameters as :

a=46\\d=42-46=-4

So , Let's calculate how many terms are there as :

⇒ a_n=a +(n-1)d

⇒ -450=46 +(n-1)(-4)

⇒ -496=(n-1)(-4)

⇒ \frac{-496}{-4}=n-1

⇒ 124=n-1

⇒ n=125

Sum of an AP is :

⇒ S_n = \frac{n}{2}(2a+(n-1)d)

⇒ S_1_2_5 = \frac{125}{2}(2(46)+(125-1)(-4))

⇒ S_1_2_5 = \frac{125}{2}(-404)

⇒ S_1_2_5 =-25,250

Therefore , sum of sequence Find the sum of 46 + 42 + 38 + ... + (-446) + (-450) is -25,250
