Answer:

NF = 16

Step-by-step explanation:

Since N is the incenter of ΔABC then ND = NE = NF

ND = NE ⇔ 6x - 2 = 3x + 7 ⇔ 6x - 3x = 7 + 2 ⇔ 3x = 9 ⇔ x = 3

Now , we calculate ND:

ND = 6(3) - 2 = 18 - 2 = 16

and because NF = ND then NF is also equal to 16

f(x) = x + 3

<u>Step 2: Find</u>

  1. Swap:                                                                                                                 x = y + 3
  2. [Subtraction Property of Equality] Isolate <em>y</em>:                                                      x - 3 = y
  3. Rewrite:                                                                                                             f⁻¹(x) = x - 3

The sum of 6 consecutive integers is 270. What is the second number in the sequence?
Rina8888 [55]
N+(n+1)+(n+2)+(n+3)+(n+4)+(n+5)=270
We use these terms to represent the first six consecutive integers in the sequence
Now we group like terms:
6n+15=270
Minus 15 from both sides of the equation
6n=255
n=42.5 which is not an integer
Is this a joke question?
Besides that, the 2nd number will be 43.5
