Step-by-step explanation:
Given the formula
a(n+1)=an−3
The first term a(1) = 31
<u>For</u><u> </u><u>the</u><u> </u><u>second</u><u> </u><u>ter</u><u>m</u>
a(2)
We have
a( 1 + 1) = a(1) - 3
a(2) = 31 - 3
a(2) = 28
<u>For</u><u> </u><u>the</u><u> </u><u>thir</u><u>d</u><u> term</u>
a(3)
We have
a(2+1) = a(2) - 3
a(3) = 28 - 3
a(3) = 25
<u>For</u><u> </u><u>the</u><u> </u><u>four</u><u>th</u><u> term</u>
a(4)
That's
a(3+1) = a(3) - 3
a(4) = 25 - 3
a(4) = 22
Hope this helps you
Answer:
15) <u><em>y= 1/2 + 3.75</em></u>
16) <u><em>y = x</em></u>
Step-by-step explanation:
For #15)
<em>Equation used: y=mx+b ; Slope: y₂ - y₁ / x₂ - x₁</em>
1) First, you need to pick any 2 points on the graph. I'll use (6,3) and (8,4).
2.1) Then you'll use the <em>slope </em>equation to find the slope (m) of your equation.
(y) ~ 4 - 3 = 1
(x) ~ 8 - 6 = 2
Slope= 1/2
3) So from the look of the answers, the y here is 3.75 so you can trust that.
4) The final equation is <u><em>y= 1/2 + 3.75</em></u>
<u><em /></u>
For #16)
Use the same steps as #15. You can still choose whatever points/plots you want. Ima use (5,4) and (6,5).
(y) ~ 4 - 3 = 1
(x) ~ 6 - 5 = 1
slope= 1 or x
Answer: y=x
<em>Your welcome for the answer! <3</em>
Pretty sure it’s the bottom right option
