A) solve for b. a=1/2ab b) evaluate when a=18 and a=3/2

A = 18 and a = 3/2

A = 1/2ab

18 = 1/2 x 3/2 x b

18 = 3/4 x b

6 = b/4

Therefore b = 24

Hope this helps you!

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
