Write an explicit formula for the sequence -3, 1, 5, 9 ... i think the answer is a_n=-3+4(n-1) i just need someone to double check me :)

Answers

Answer 1
Answer:

Answer:

you are correct

Step-by-step explanation:

The sequence has a common difference between consecutive terms

d = 9 - 5 = 5 - 1 = 1 - (- 3) = 4

This indicates the sequence is arithmetic with explicit formula

a_(n) = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = - 3 and d = 4, thus

a_(n) = - 3 + 4(n - 1) = - 3 + 4n - 4 = 4n - 7

Which answer shows this equation in standard form?8 - 4(x + y) = -6x + 6

A. -10x + 4y = -2

B. 2x + 4y = -2

C. 2x + 4y = 2

D. 2x - 4y = -2

Answers

The Standard Form equation of a line has the following formula: 
ax+by=c ; a≠0 ; b≠0 ;

Then, 8 - 4x - 4y = -6x + 6 ;
-4x + 6x - 4y = 6 - 8 ;
2x - 4y = - 2 ;

Let f(x) =x squared +3x-4 and g(x) =x+5. Find f(x) times g(x).

Answers

Answer:

x^3 + 8x^2 + 11x - 30

Step-by-step explanation:

f(x) times g(x) = (x^2 +3x-4)(x+5)

= x^3 + 5x^2 + 3x^2 + 15x - 4x - 20

= x^3 + 8x^2 + 11x - 30
