It's a simple linear equation in 'n'. There's only one number that 'n' can be
that will make the equation a true statement. That number is called the
'solution' to the equation. Here's one way to find it:
You said that <u> -7n - 4 = 24</u>
Add 4 to each side: -7n = 28
Multiply each side by -1 : 7n = -28
Divide each side by 7 : <em>n = -4</em>

Answer:
Number of students want to go to Theme Park = 75
Step-by-step explanation:
Note: The given question is incomplete. Complete question is as follow.
Given:
Number of sample student = 30
Place Number of students want to go
Theme Park 10
Theater 5
Sports Center 8
Seaside 7
Find:
How many students want to go to Theme Park.
Computation:
⇒ Probability for students want to go to Theme Park = 10 / 30
⇒ Probability for students want to go to Theme Park = 1 / 3
⇒ Number of students want to go to Theme Park = [1 / 3]225
⇒ Number of students want to go to Theme Park = 75

Answer:
$1571
Step-by-step explanation:
If we assume that y is profit in dollars, the maximum value of y is revealed by a graph to be ...
ymax = $1571
The maximum profit the company can make is $1571 at a selling price of $45 each.
_____
The function can be written in vertex form as ...
y = -(x^2 -90x) -454
y = -(x^2 -90x +45^2) -454 +45^2
y = -(x -45)^2 +1571
Because the leading coefficient is negative, we know this vertex represents a maximum. (x, y) = (45, 1571) at the vertex. Maximum profit is $1571.
