1. two pieces of equipment were purchased for a total of $4000. if one piece cost $850 more fean
the other, find the price of the less expensive piece of equipment. assume all data ze 2002
to two significant agits unless grezier 20curacy is given

$1,575

Step-by-step explanation:

x = the cost of the less expensive piece of equipment

x+850 = the cost of the more expensive piece of equipment

x + (x+850) = 4,000 the.     two pieces together cost 4,000, so I added up the cost of the less expensive piece and the more expensive piece, and equaled it to 4,000

solve the equation:

x + (x+850) = 4,000

2x+850=4,000

2x=3,150

÷2

x=1,575

no he doesnt because "-16' is negatiive

step-by-step explanation:

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
