If 200 beads cost 48 dollars how much does 25 cost

Mathematics
1 answer:
Shalnov [3]3 years ago

200 beads = $48, so 48÷200 = $0.24, which is the cost of one bead.

If the cost of 1 bead is $0.24, then 25×0.24 = $6

25 beads cost $6

Step-by-step explanation:

y=-x-6

y=x-4

----------

-x-6=x-4

-x-x-6=-4

-2x-6=-4

-2x=-4+6

-2x=2

Identify the coordinates of the vertex of f(x) = 3x2 + 12x − 8, and identify whether it is an absolute minimum or absolute maxim
DaniilM [7]

The vertex of f(x) = 3x^2 + 12x − 8 is (2,28) absolute minimum

<h3>How to determine the vertex?</h3>

The equation is given as:

f(x) = 3x^2 + 12x − 8

Differentiate the function

f'(x) = 6x + 12

Set to 0

6x + 12 = 0


Divide through by 6

x + 2 = 0

Solve for x

x = -2

Substitute x = -2 in f(x) = 3x^2 + 12x − 8

f(2) = 3 *2^2 + 12 *2 − 8

Evaluate

f(2) = 28

This means that the vertex is (2,28)

A quadratic function is represented as:

f(x) =ax^2 + bx + c

When a is positive, then the vertex of the function is an absolute minimum.

This means that f(x) = 3x^2 + 12x − 8 has an absolute minimum vertex because 3 is positive
