Hildy had 2.5 oz of liquid for a science experiment. the instructions said that the experiment needed 3 oz of liquid. she went to the cabinet and got an additional 7.5 oz of liquid. did hildy get a reasonable amount of liquid out of the cabinet?

a. yes, hildy got a reasonable amount of liquid because she needed a total of 7.5 oz (2.5 × 3 = 7.5).

b. no, hildy did not get a reasonable amount of liquid because she only needed 0.5 oz (3 – 2.5 = 0.5).

c. no, hildy did not get a reasonable amount of liquid because she only needed 5.5 oz (3 + 2.5 = 5.5).

a: 1/6, j: 1/4

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
