Remember you can do anything to an equation as long as you do it to both sides
2x+3(x-4)=x-20
first distribute
2x+3(x)+3(-4)=x-20
2x+3x-12=x-20
5x-12=x-20
minus x both sides
4x-12=-20
add 12 to both sides
4x=-8
divide both sides by 4
x=-2
Answer:
As the described function, we want to find vertical asymtotes, we find the value of x so that the denominator is equal to 0.
Here, (x - 2)(x + 6) = 0
=> x = 2, x =-6
=> Option C is correct.
Hope this helps!

The average rate of change of <em>f(x)</em> on -3 ≤ <em>x</em> ≤ 3 is given to be
(<em>f</em> (3) - <em>f</em> (-3)) / (3 - (-3)) = -2.5
If <em>f</em> (-3) = 14, then
(<em>f</em> (3) - 14) / (3 + 3) = -2.5
(<em>f</em> (3) - 14) / 6 = -2.5
<em>f</em> (3) - 14 = -15
<em>f</em> (3) = -1
Answer: 20 ;)
Step-by-step explanation:
<h2>Required Answer:</h2>

<h2 /><h2>Question:</h2>
- There are 20 classrooms in the high school with 30 students in each class. How many students are in the school?
<h2>To find:</h2>
<h2>Given:</h2>
- Total no. of classrooms = 20
- students in each class= 30
<h2>Answer:</h2>
- Total no. of students in school= Total no. of classrooms×students in each class
- Total no. of students in school=20×30
- Total no. of students in school=600
best of luck! ^_^
