Find the first four terms of the sequence given by the following an=57-4(n-1),n=1,2,3
Crazy boy [7]

Answer:

57, 53, 49, 45

Step-by-step explanation:

Substitute for the n for n=1,2,3,4 so the first term is 57-4(1-1) so =57-4(0) so

a(1) = 57-0 = 57  so that is the 1st term

2nd term 57-4(2-1) so =57-4(1) so   a(2) = 57-4 = 53, etc.

Learning task3:A. Change the following into the form of f(x) = mx + b
mr_godi [17]

Answer:

1. f(x) = 3x + 7

2. f(x) = -\dfrac12x + 2

3. f(x) = x + 5

4. f(x) = -2x - 5

5. f(x) = -\dfrac32 x + 2

Step-by-step explanation:

Rearrange all the equations to make y the subject,
then substitute f(x) for y:

1.   y - 3x = 7

Add 3x to both sides:

⇒ y = 3x + 7

⇒ f(x) = 3x + 7

2.   2x + 4y = 8

Subtract 2x from both sides:

⇒ 4y = -2x + 8

Divide both sides by 4:

⇒ y = -\dfrac12x + 2

⇒ f(x) = -\dfrac12x + 2

3.   -x + y = 5

Add x to both sides:

⇒ y = x + 5

⇒ f(x) = x + 5

4. y + 5 = -2x

Subtract 5 from both sides:

⇒ y = -2x - 5

⇒ f(x) = -2x - 5

5.   3x + 2y - 4 = 0

Subtract 3x from both sides:

⇒ 2y - 4 = -3x

Add 4 to both sides:

⇒ 2y = -3x + 4

Divide both sides by 2;

⇒ y = -\dfrac32 x + 2

⇒ f(x) = -\dfrac32 x + 2
