Answer:
b
Step-by-step explanation:
All you have to do is subtract
Answer:
y = t/31 - d/31
Step-by-step explanation:
Solve for y:
d + 12 y = t - 19 y
Subtract d - 19 y from both sides:
31 y = t - d
Divide both sides by 31:
Answer: y = t/31 - d/31
Answer:
Option a - f(x)=20x
Step-by-step explanation:
Given : For a certain function f = f(x), we know that f is proportional to x and that the constant of proportionality is 20.
To Find : A formula for f ?
Solution :
We have given that,
f is proportional to x i.e.
This implies
Where, k is the proportionality constant
The constant of proportionality is 20.
So,
On comparing with, f = f(x)
Therefore, The formula of f is
So, Option a is correct.

Answer:
A
Step-by-step explanation:
When the decay is exponential, the remaining amount is the same fraction for every interval. When the decay is linear, the change in amount is the same for every interval.
In Table A, the fraction remaining is 8/16 = 4/8 = 2/4 = 1/2. Table A shows exponential decay.
In Table B, the amount of change is 12-16 = 8-12 = 4-8 = -4. Table B shows linear change.
