Answer:
A function of the form 
, where 'm' and 'b' are real numbers, is called a <u>linear function.</u>
Step-by-step explanation:
A linear function is one in which the 
value of the function varies linearly with 'x'. When we plot a linear function on a graph, the resulting curve is always a straight line with the slope of the line being constant.
A linear function is of the form:
, where, 'm' and 'b' are real numbers.
The degree or the highest exponent of 'x' in a linear function is always equal to 1.
Therefore, a function of the form , where 'm' and 'b' are real numbers, is called a <u>linear function.</u>
Solving a system of equations we will see that they sold 80 adult tickets.
<h3>how many adult tickets were sold?</h3>
To solve this, we need to solve a system of equations. To define said systems of equations, we first need to define the variables, we will use:
- x = adult tickets sold.
- y = student tickets sold.
They sold 20 more adult tickets than student tickets, then:
x = y + 20
And they collected a total of $880, then:
x*$8 + y*$4 = $880
The the system of equations is:
x = y + 20
x*$8 + y*$4 = $880
Isolating y on the first equation we get:
y = x - 20
Replacing that on the other equation we get:
x*$8 + (x - 20)*$4 = $880
Now let's solve that for x.
x*$12 - $80 = $880
x*$12 = $880 + $80 = $960
x = $960/$12 = 80
They sold 80 adult tickets.

The perimeter is D because you have to add all the sides up. 2 + 2 and 3 plus 3 equals 10x and then 8 + 8 and 2 + 2 equals 20 so 10x- 20.
X=3
because a triangle with side length 3,4,5 is right angled
AC＝AC (reason: reflexive property)
