Answer: $4$ pairs

Step-by-step explanation:

Given

Profit on selling 'x' pairs of shoes is $P(x)=-4x^2+32x-39$

Find the derivative of the function to find out the critical points

$\Rightarrow -8x+32=0\\\Rightarrow x=4$

Thus, for 4 pair of shoes profit is maximize.

5x + 9 = x - 23 find X

Doss [256]

5x + 9 = x - 23

move x to the other side

sign changes from +x to -x

5x-x+9= x-x-23 ( combine like terms)

5x-x+9= -23

4x+9= -23

move -9 to the other side

4x+9-9= -23-9

4x= -23-9

4x= -32

divide both sides by 4 to get x by itself

4x/4= -32/4

answer:

x= -8

Find the exponential equation for the given information. Pls help

nikitadnepr [17]

Answer:

y = 12 $(2.9)^{x}$

Step-by-step explanation:

The standard form of the exponential function is

y = a $(b)^{x}$

Find a and b by substituting ordered pairs from the table into the equation

Using (0, 12 ), then

12 = a $b^{0}$ ( $b^{0}$ = 1 ), so

a = 12, then

y = 12 $b^{x}$

Using (1, 34.8 ) , then

34.8 = 12 $b^{1}$ ( divide both sides by 12 )

b = 2.9

Thus exponential function is

y = 12 $(2.9)^{x}$
