The graph of the function

Mathematics

Answer:

<h2>D. The function is decreasing for all real values of x where x < 1.5</h2>

Step-by-step explanation:

The graph show a parabola, which is characterized for having decreasing and increasing interval, due to its behaviour.

In addition, decreasing means that while x-values increase, y-values decreases. On the other hand, increasing means that while x-values increase, y-values decrease.

You can observe in the graph that the function decreases, from negative infinite to x=1.5, and increases from x=1.5 to positive infinite. Based, on this deduction, we can say that the right answer is D, because it describes this decreasing behaviour for all x < 1.5, which is complete true.

Answer:

  D.The function is decreasing for all real values of x where x < 1.5

Step-by-step explanation:

The vertex is at x=1.5, so the function is decreasing on one side of that and increasing on the other. Any answer choice with some number other than 1.5 as the boundary of increasing/decreasing can be ignored.

Of course one descriptor (<em>increasing</em> or <em>decreasing</em>) is not applicable for any interval that includes the point where the slope changes sign.

The function is decreasing for all real values of x where x < 1.5.

The function p(x) = - 2(x-9)2 + 100 is used to determines the profit on T-shirts sold for x dollars. What would the profit from
dolphi86 [110]

ANSWER

$28

EXPLANATION

The profit function is given as:

p(x) =  - 2 {(x - 9)}^{2}  + 100

where x is the price of the T-shirt in dollars.

To find the profit on a T-shirt whose price is $15, we substitute x=15 into the function and simplify.

p(15) =  - 2 {(15 - 9)}^{2}  + 100

We simplify to get:

p(15) =  - 2 {(6)}^{2}  + 100

p(15) =  -72+ 100

p(15) =  28

4688-3) -30X-5 CX-5)
pshichka [43]

Answer:

x = 13/3

Step-by-step explanation:

4(8x-3) - 30x = 5(x-5)

Distribute

32x - 12 - 30x  = 5x -25

Combine like terms

2x -12 = 5x-25

Subtract 2x from each side

2x-12-2x = 5x-2x -25

-12 = 3x-25

Add 25 to each side

-12+25 = 3x-25+25

13 = 3x

Divide each side by 3

13/3 = x
