amachine cost $45000 to purchase, fuel and minor maintenance are estimated to cost $12.34 per operating hoour (those hours when the engine is operating and machine is doing work). a set of tires cost $3'200 to reace, and their estimated life is 2,800 hr use the machine is expected to last for 8,400hr , after which it will sold at a price equal to 10% if original purchase price. a final set of new tires will not be purchased before the sale. how much should the owner of the machine charge per hour of use, if it is expected that the machine will operate 1,400hr per year? the company's cost of capital rate is 7%.

if x decreases by 4 then y increases by 10

step-by-step explanation:

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is
