Solve the quadratic equation numerically (using tables of x- and y- values). -4x=-x2+12

Levart [38]

-4x=-x2+12 should be written -4x=-x^2+12, with " ^ " representing exponentiation.

You are to invent a table of x values and find the difference between -4x and -x^ 2+12. The smaller the difference, the closer you are to finding the correct root, x.

To get you started:

x -4x x^2+12 difference
--- ------------ ---------------- --------------
2 -8 16 24 (pretty bad!)
-4 16 28 12 (better)
-10 40 112 72 (much worse)

To answer this problem correctly, you must present such a table, even tho' it'd be faster to use the quadratic formula (or some other method) to find x.

Mary has an office-supplies budget of $150 for

tatyana61 [14]

Part a)

The inequality that represents the number of folders f and notebooks n she can purchase is $2.15f+4.60n\leq 150$

Part b)

The graph is attached in figure.

Step-by-step explanation:

Part a)

Total budget of Mary = $150

Price of each folder = $2.15

Price of each notebook= $4.60

Let f represent folder and n represent notebooks the inequality will be:

$2.15f+4.60n\leq 150$

We are using less than or equal to (≤) because the budget is 150. the total price should be less than or equal to 150.

So, inequality that represents the number of folders f and notebooks n she can purchase is $2.15f+4.60n\leq 150$

Part b)

Graph the inequality 2x – 3y = 12

We need to graph the inequality but in the given question the inequality sign is missing.

Considering less than equal to (≤) sign

2x – 3y <= 12

The graph is attached in figure below.
