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.

4y/5b=L+s solve for B

krek1111 [17]

Answer:

$b = \frac{4y}{5l + 5s}$

Step-by-step explanation:

$\frac{4y}{5b} = l + s$

multiplying through by the L.C.M. which is 5b

$\frac{4y}{5b} \times 5b = (l + s) \times 5b$

cancel out

4y =5bL+ 5bs

factorizing b out

4y=b ( 5L +5s ).

making be the subject by dividing through by ( 5L+ 5s )

$\frac{4y}{5l + 5s} = \frac{b(5l + 5s)}{5l + 5s}$

$b = \frac{4y}{5l + 5s}$
