(7.3 X 106) + (2.4 X 107)
(4 X 104)

104607.4

Step-by-step explanation:

(7.3 x 106) = 773.8

(2.4 x 107) = 249.6

(4 x 104) = 416

773.8 + (249.6)(416)

773.8 + 103833.6

= 104607.4

$450

step-by-step explanation:

first, you have to multiply 150x2=300

next, you have to add 150+300= 450

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
