Hello, Marymack!
We know that in a geometric sequence defined by
and
, the sum can be calculated the following way:
On my calculator it says 1/17 but I’m not sure you can try that and if it isn’t the right answer then im not sure good luck tho
Answer:
6
Step-by-step explanation:
Let x=4
Let y=1
4-1=3
8-2=6
(4,1)(7,-2)
slope = (-2 - 1) / (7 - 4) = -3/3 = -1
Answer: 1. 2 2. 4 3. 9
Step-by-step explanation: Hi there!
First, we need to set up our equation by combining like terms.
x+2x+4x+1=15
7x+1=15
Then subtract 1 on both sides
7x=14
Then divide by 7
x=2
So x=2
Put that into all of the x values on the piece of steel to get 2, 4, 9.
Hope this answer helps you!
