Answer:

a_{n} = 7n - 2

Step-by-step explanation:

The n th term of an arithmetic sequence is

a_{n} = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 5 and d = 12 - 5 = 7, thus

a_{n} = 5 + 7(n - 1) = 5 + 7n - 7 = 7n - 2

How do you solve this do i need to plpug in the formula
Sergeeva-Olga [200]

Answer:

  B.  -2, 2

Step-by-step explanation:

Apparently, we're to presume that f(x) is the line that is graphed. It has a y-intercept of +1 and a slope (rise/run) of 1/2. Its equation is ...

  f(x) = 1/2x +1

If we want points of intersection, we want to solve the equation f(x) = g(x) for the values of x that make it so.

  1/2x +1 = √(x +2)

Squaring both sides, we get ...

  1/4x² +x + 1 = x +2

  1/4x² = 1 . . . . . . . . . . . . subtract x+1 from both sides

  x² -4 = 0 . . . . . . . . . . multiply by 4, subtract 4

  (x -2)(x +2) = 0 . . . . factor the difference of squares

  x = -2, 2 . . . . . . . . . values of x that make the factors zero

The solutions to f(x) = g(x) are x = -2 and x = 2.

_____

<em>Additional comment</em>

The attached graph shows the x- and y-values at the points of intersection. The solutions to f(x) = g(x) are only the x-values, -2 and 2.

The square of (ax +b) is ...

  (ax +b)² = a²x² +2abx +b²

The point-slope equation of a line is ...

  y = mx + b . . . . . line with slope m and y-intercept b

The softball team is selling hats. John bought 3 for $24.00. Stacey bought 5 for $40.00. Jim bought 2 for $16.00.
iren2701 [21]

The value of the hats bought by John, Stacey, and Jim are $8 per hat. This shows a proportional relationship.

<h3>What is a proportional relationship?</h3>

It should be noted that a proportional relationship is one where it van be expressed as y = kx.

In this case, John bought 3 for $24.00. This will be:

= $24 / 3

= $8 per hat

Stacey bought 5 for $40.00. This will be:

= $40 / 5

= $8 per hat

Jim bought 2 for $16.00. This will be:

= $16/2

= $8 per hat

Therefore, it's a proportional relationship.
