Which graph represents the solution set of the compound inequality -5 < a -15 < 2

We are given the inequality,

Now let us simplify this to get the value of a,

Adding 15 to both the sides,

So we have a>10 and a<17

One more thing that we need to look at is whether we will have close dots or open dots at 10 or 17.

If we have "=" sign along with inequality sign (≤ or ≥) then we use closed dot.

If we dont have "=" sign along with inequality sign (< or >) then we use open dot.

In our case we use open dot , since we dont have "=" sign.

So Answer will be option third, line starting from 10 to 17 with open dots at 10 and 17.

i can't see the picture : /

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
