Serhud [2]3 years ago
6 0

Answer:

1. 2x^2-15x+17=0

2. 2.4x^2-3.5x-2.2=0

3. -4.2x^2+6.8x-2=0

Step-by-step explanation:

Standard form is written as ax^2+bx+c=0. To write each equation in standard from:

  • Distribute into any parenthesis
  • Move terms across the equal sign with inverse operations
  • Combine any like terms

1.

2(x-3)^2=3x+1\\\\2(x^2-6x+9)=3x+1\\\\2x^2-12x+18=3x+1\\\\2x^2-15x+17=0

2.

2.4x^2-3.5x=2.2\\\\2.4x^2-3.5x-2.2=0

3.

6.8x - 2 = 4.2x^2\\\\-4.2x^2+6.8x-2=0

Which recursive formula can be used to generate the sequence shown, where f(1) = 5 and n > 1?
Degger [83]

The recursive formula a_n = a_{n-1}-6 can be used to generate the shown sequence

Step-by-step explanation:

Recursive formula is the formula that is used to generate the next term of a sequence using previous term.

The general form of arithmetic sequence's recursive formula is:

a_n = a_{n-1}+d

Given

5,-1,-7,-13,-19

Here

a_1 = 5\\a_2 = -1\\a_3 = -7

First of all we have to find the common difference of the sequence.

So,

d = a_2 -a_1 = -1-5 = -6\\d = a_3-a_2 = -7+1 = -6

Putting the value of d in the general recursive formula

a_n = a_{n-1}-6

Hence,

The recursive formula a_n = a_{n-1}-6 can be used to generate the shown sequence
