Answer:
x=-2 (the actual solution)
x=-5 (the extraneous solution)
Step-by-step explanation:
First step is to isolate the radical part (the part with the square root).
So we will add 4 on both sides first:

To get rid of square we are going to square both sides:

We are going to expand right hand side (you can use "F.O.I.L":

Subtract x on both sides and subtract 6 on both sides:

Combine like terms:

We will now factor:
(Since 2(5)=10 and 2+5=7)
Set both factors equal to 0:
x+2=0 or x+5=0
Solve first equation by subtracting 2 on both sides to obtain x=-2.
Solve second equation by subtracting 5 on both sides to obtain x=-5.
Now let's check to see if these are both actually indeed solutions to the equation we began with:
for
:



is a true equation so
is indeed a solution.
for
:



is false so
is what we call the extraneous solution.
Answer:
$225 = $15 a + $ 10 c
Step-by-step explanation:
Given,
Total price = $225
Cost of concert ticket for adults= $15
Cost of concert ticket for children = $10
System of equation to represent scenario
a is variable for adult
c is variable for children
Now,
Total price = $15 a + $ 10 c
$225 = $15 a + $ 10 c
If the analyst wants an average of all fastballs, it is not useful to measure other pitches, nor is it useful to limit it to a subset of the pitchers.
So, the sample should draw from all fastballs.
