So, Jerome bought a total of 80 cards (8x10) out of which he gave out 30 cards (3x10) so he has 50 cards left. (80-30)
Answer:
y=1300-285x
Step-by-step explanation:
1300-575=725
725/5=145
y=1300-285x
Answer:
(D) 
Step-by-step explanation:
Two variables x and y are proportionally related if they can be written in the form y=kx, where k is the constant of proportionality.
From the given options, if 
(B)
is of the form y=kx
(C)
is of the form y=kx with as 
in its lowest form.
(C)
is of the form y=kx with as 
in fractional form.
On the Contrary,
In Option D, does not represent a proportional relationship between x and y. The constant of proportion is supposed to be a product of x.
Answer:
1) .8333 2) 2.6666 3) 2 4) 1.5
Step-by-step explanation:
I just used a calculator.
Answer:
1. The growth rate is 2
2. The sample is losing half its mass, so the decay factor is 1/2 or 0.5
Step-by-step explanation:
The growth and decay factor in an exponential function is the number that is being multiplied to the power of x
- It is a growth rate when that number is greater than 1
- It is a decay rate when the number is less than 1
- If it's 1 then it's not growing or decaying
- If it's 0 you will have an answer of 0
