Two quantities vary inversely. if the value of the first is 15 when the value of the second is 18, find the value of the
second quantity when the first is 10.

13

Step-by-step explanation:

When the first quantity is 15, the second quality is 18. This means that the second quality is 3 more than the first quality.

If the first quantity is 10, what is the value of the second quantity?

10 + 3 = 13

the answer is simply just 6n add the two together as they have an n

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
