First equation:
5(x+1)=20 —— distribute the 5 to the x and 1
5x+5=20 ——- subtract 5 from 20
5x=15 ———— divide by 5 from both sides
X=3 ————— answer
Second equation:
5x+1=20——— subtract 1 from 20
5x=19 ———— divide by 5 from both sides
X=19/5———— answer in fraction form
X=3.8————- answer in decimal form
The correct answer is B. -2/3 that is the slope
If we deal with Natural numbers then the range is
1 ≤ p ≤ 5
I believe the 4th one
an=145+an-1 and a1=20
I can see it goes through the point (2, 2)
b = 6 then
solved it the lazy way, graphically with desmos and a slider for b, see screenshot
