You need to multiply the amount it is dropping per day by the number of days, so you would have 0.3d
You would then need to subtract that amount from the current level of 25 feet.
Now you have 25 - 0.3d.
This total needs to be greater than or equal to 13 feet.
25 -0.3d ≥ 13
Answer:
f(x) = 4x
Step-by-step explanation:
-2 x 4 = -8
-1 x 4 = -4
0 x 4 = 0
1 x 4 = 4
The final score is 38. I got that answer by taking the total amount and subtracting the total score from the other game.
Plotting the points could help you notice that they lie along a parabola. In particular, you can see that
is always 4 more than
.
So, the relation is
![y=x^2+4](https://tex.z-dn.net/?f=y%3Dx%5E2%2B4)
-k + 0.03 + 1.01k = -2.45 - 1.81k
Multiplying through by 100, we have
-100k + 3 + 101k = -245 - 181k
