Suppose it has been determined that the sales at Ewing Gallery decline after the end of an advertising campaign, with daily sales given by S\:=\:2100\left(2^{-0.2x}\right)S = 2100 ( 2 − 0.2 x ) , where S is in dollars and x is the number of days after the campaign ends. What are the daily sales 5 days after the end of the campaign?

$1050 is the daily sales 5 days after the end of the campaign.

Step-by-step explanation:

We are given the following in the question:

where S is the daily sales in dollars and x is the number of days after the campaign ends.

We have to find the value of the daily sales 5 days after the end of the campaign.

We put x  = 5 in the equation:

Thus, $1050 is the daily sales 5 days after the end of the campaign.

60 for the first and 130 for the second

step-by-step explanation:

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.
