Answer:
-3
Step-by-step explanation:
The general rule can be found by noticing patterns such as the numbers get smaller by 3 from the first term 3 towards the next 0 and towards next one -3
term 1: 3
term 2 : 3 -3 = 0
term 3 : 0 -3 = -3
The general rule of 3;0;-3 is subtract 3
If you just type that exact equation into a calculator it gives you the same answer as well
Let's say the savings in your account are given by $V, the number of weeks by n and the starting balance by $x:
V = x + 200n
Now if after saving for 4 weeks you have $1700 in your account, then:
1700 = x + 200*4
1700 = x + 800
x = 900, thus your starting balance is $900
Using this information we can now write up the general equation for the savings at the end of each week:
V = 900 + 200n
Answer:
(-1, -4)
Step-by-step explanation:
In the graph:
The reflected point is 1 unit below 0 so x = -1
The reflected point is 4 units to the left of 0 so y = -4
Since coordinates are in (x, y) the coordinates are (-1, -4)
