Answer: <em>4x+2</em>
Step-by-step explanation:
<em>Let's take our equation to start</em>
<em>2(3x+5)-2(x+4)</em>
<em>Distribute the 2 and -2 into the parenthesis</em>
<em>6x+10-2x-8</em>
<em>Now combine the like terms</em>
<em>6x-2x=4x</em>
<em>10-8=2</em>
<em>4x+2</em>
f(x) = 2|-4x + 5| - 4
Solution to Example 3
<span><span><span>The range of |-4x + 5| is given by
|-4x + 5| ≥ 0
</span><span>Multiply both sides of the inequality by 2 to obtain
2 |-4x + 5| ≥ 0
</span><span>Add -4 to both sides of the above inequality to obtain
2 |-4x + 5| - 4 ≥ - 4
</span></span><span>The range of 2 |-4x + 5| - 4 may also be written in interval form as follows
[-4 , ∞)</span></span><span>The domain of f above is the set of all values of x in the interval ( -3 , +∞)

since it states that they hired 2 buses
and the equation is coming up with the total number of students ,
the letter b is for the number of students that rode each bus
I believe it’s A I had this question
