<h2>What is the rate of change of the line through (3, -5) and (-5, 3)?..........</h2>
Answer:
number of students in a van=12
number of students in a bus=52
Step-by-step explanation:
let number of students in a van=x
number of students in a bus=y
1x+6y=324 ...(1)
9x+3y=264 ...(2)
multiply (2) by 2
18x+6y=528 ...(3)
(3)-(1) gives
17x=204
x=204/17=12
put in (1)
12+6y=324
6y=324-12=312
y=312/6=52
Answer:
---- Set Builder
(50, ∞) ---- Interval Notation
Step-by-step explanation:
Given
x > 50
Required
Write as a
- Set builder
- Interval notation
As Set Builder:
x > 50 means that x is an integer and x is greater than 50.
In set builder notation, integers are represented with z.
So, the above can be represented as:

This translates to:
x is a member of the set of integers such that x is greater than 50
As Interval Notation:
In interval notation, we make use of brackets to represent the intervals.
In this case > is represented by (a,b)
Where a and b are the intervals of the notation
Since x > 50, then a = 50 and b = ∞ because we only know the starting point and not the end point.
<em>Hence: x > 50 in interval notation is (50, ∞)</em>
