nevsk [136]

Answer:

After about 12 months both Caitlyn and Santos will have the same balance of 150 dollars in their bank account.

Step-by-step explanation:

Caitlyn's saving:  -5x+210

Santos' saving: 5x+90

To know when the total amount in their bank account is the same you would need to make these linear equations equal to one another.

-5x+210 = 5x+90

(Add 5x on both sides)

210=10x+90

(Subtract 90 from both sides)

120=10x

(Simplify)

x=12

After about 12 months their total savings should be the same. To check what their balance will be plug the x value of 12 into both of these equations. This should give 150 as your answer for both equations.

Answer:

  quadratic

Step-by-step explanation:

The x-values are sequential, so we can look at the y-values.

Differences from one to the next are ...

  -7, -1, 5, 11, 17

And the differences of these numbers are ...

  6, 6, 6, 6

When <em>second</em> differences are constant, the sequence can be produced by a <em>second</em>-degree (quadratic) polynomial.

__

Here, that polynomial is ...

  y = 3x² +2x -1

The regression functions of a graphing calculator can help you find the appropriate formula.
