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 second differences are constant, the sequence can be produced by a second-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.

Solve this inequality. 8x + 6 less than or equel to 54

Step2247 [10]

Answer:

$x\le 6$

Step-by-step explanation:

We need to solve the given inequality $8x+6\le 54$ ....(1)

Subtract 6 on both sides of the equation as :

$8x+6-6\le 54-6\\\\8x\le 48$

Dividing both sides of the equation by 8 such that,

$x\le 6$

So, the value of x is less than equal to 6. Hence, this is the required solution.
