First term: -9
Common difference: 7
a(n) = -9 + 7(n-1), for n = {1, 2, 3, ... }
Check: what is the first term? let n=1. Then a(1) = -9 + 7(1-1) = -9.
This is correct.
Last one is A, (3,4) and (5,12) because that's where the lines meet therefore it is a solution and this graph consists of two solutions.
Answer:
<em>3</em>
Step-by-step explanation:
GCF means greatest common factor. It is the largest number that 3, 15, and 9 are divisible by.
3 is divisible by only 1 and 3
15 is divisible by 1, 3, 5, and 15
9 is divisible by 1, 3, and 9
The largest number 3, 15, and 9 are divisible by is 3.
The GCF of 3, 15, and 9 is 3.
Let x equal the larger number
Let y equal the smaller number
x+y=63
x=y+11
Sub the second equation into the first equation and solve for y
y+11+y=63
2y+11=63
2y=63-11
2y=52
y=52/2
y=26
Sub y into the second equation
x=y+11
x=26+11
x=37
Hope this helps!
The answer is (-7, -12).
Attached is the graph to show the answer.
