Answer
Part A
1 - 1
2 - 3
3 - 6
4 - 10
5 - 15
Part B
Now plot these points on the coordinate plane
(1,1) (2,3) (3,6) (4,10) (5,15)
Part C
It is NOT a linear function
It cannot be simplified more than that. hope this helps!
Answer:
18, 19, 20, 21
Step-by-step explanation:
Just like any of these problems, we should start by forming an equation for us to get a reference and plug in. We'll be using x as our variables.
As we have four consecutive integers (and not multiples) we can assume that the integers will be x, x+1, x+2, and x+3.
The sum of the two largest integers we have equals: n+2 + n+3 = 2n+5
and three times the sum of the two smallest = 3(n + n+1) = 6n+3
and the sum of t he two largest subtracted from three times the sum of the two smallest = (6n+3) - (2n+5) = 4n-2
4n-2=70
4n=68
n = 18.
n = 18, n+1 = 19, n+2 = 20, n+3 = 21
To get the average, you must add all together and divide by the amount of numbers there are
(-4 - 6 - 3 - 1 + 0 + 2 - 1 - 3)/ 8
(-16)/8 = -2
-2 is your average
hope this helps
