Given equation is :
=0
Taking out
common we get,
=0
Now solving this we get,
As 11 is not factor-able, we will solve it using the formula,

a=1 b=5 and c=-11
we get,
and 
This is an absolute value function.
Answer:
<h2>
a ∈ (-∞, -3></h2>
Step-by-step explanation:
<h3>-
21 ≥ 3(a - 7) + 9</h3><h3>
- 21 ≥ 3a - 21 + 9</h3>
+21 +21
<h3>
0 ≥ 3a + 9 </h3><h3>
3a + 9 ≤ 0</h3>
-9 -9
<h3>
3a ≤ - 9</h3>
÷3 ÷3
<h3>
a ≤ -3 </h3><h3>
a ∈ (-∞, -3></h3>
To do this you have to divide 135 miles by 5 hours. You will get the answer of 27 miles per hour.
