If you would like to know how many of each type of ticket were sold, you can calculate this using the following two equations:
a ... the number of drakes fan club tickets
s ... the number of no members tickets
$550 = a * $20 + s * $25 ... 550 = 20 * a + 25 * s
a + s = 25 ... a = 25 - s
__________________
550 = 20 * a + 25 * s
550 = 20 * (25 - s) + 25 * s
550 = 20 * 25 - 20 * s + 25 * s
550 - 20 * 25 = 5 * s
550 - 500 = 5 * s /5
s = 50 / 5
s = 10 tickets
a = 25 - s = 25 - 10 = 15 tickets
Result: There were 15 drakes fan club and 10 no members tickets sold.
Answer: The answer would be 628.24!

x = 8
x = 10
x = 11
The solution to the given algebraic expression (x - 2)(x + 10) = 13 is x = 3
An algebraic equation is the combination of variables and their coefficients(usually numbers) with arithmetic operations. The main purpose of an algebraic expression is to determine the value(s) of the variable(s).
From the given information:
(x - 2)(x + 10) = 13
x² + 10x - 2x - 20 = 13
x² + 8x -20 -13
x² + 8x - 33 = 0 (quadratic equation)
Using the quadratic formula, the values of x are - 11 and 3. Since we are considering only the positive integer only, x = 3

Answer: X=3
Step-by-step explanation:
1. expand the equation
x^2 + 10x -2x -20 = 13
2. Collect like terms
x^2 + 8x - 20 = 13
3. Simplify
x^2 + 8x = 13 + 20
x^2 + 8x = 33
x^2 = 33 - 8x
4. Substitute answers for guess and check
3^2 = 33 - (8 x 3)
9 = 33 - 24
This equation is correct therefore x = 3
If f(1) = 1 that means c is -2 because when you substitute x = 1 and when c = -2, you'll get f(1) = -2(1)+3 = -2+3 = 1
So the constant c is -2 and that means the value of f(-4) is
f(-4)=-2(-4)+3=8+3=11
Thus, the value of f(-4) is 11.
About why does "c" have to be -2, here's the proof.
Given y = f(x), therefore.
y=cx+3
Since when x = 1 and y = 1, then Substitute x = 1 and y = 1, thus 1 = c+3
1 - 3 = c and therefore, -2 = c #
So this is the proof that c = -2
