A function is for every input, there is 1 output
aka
x never repeats with a different y
A. x doesn't repeat, it's a function
B. -8 repeats with 34 and 40, this is not a funciton (this is the answer0
C. x doesn't repeat, it's a function
D. x doesn't repeat, it's a function
answer is B
Answer:
The answer is A $100
Step-by-step explanation:
since 0 deposits is $50 and 1 deposit is $150
you do 150-50 which is 100
Answer:
Direct Variation Use y=kx. Means “y varies directly with x.” k is called the constant of variation. “y varies inversely with x.” k is the constant of variation.
Step-by-step explanation:
Given:
The principal = $ 4000
The rate of interest = 22 %
To find the loan amount a) after 1 year and b) after 3 years.
Formula
Loan amount is

where,
A be the loan amount
P be the principal
r be the rate of interest and
t be the time.
Now,
a) Taking, P = 4000, r = 22, t = 1 we get,

or, 
Again,
b) Taking, P = 4000, r = 22 and t = 4 w eget,


Hence,
a) The amount of loan after 1 year is $ 4880
and b) The amount of loan after 4 year is $ 7263.39.
Answer:
y=1.5x
b is the y intercept but it is 0 so no need to add it. y is the result
