Answer:
y = 2/3x
Step-by-step explanation:
Answer: 1/25
Step-by-step explanation:
Answer:
- final balance: A
- initial investment: P
- return rate: r
Step-by-step explanation:
The variable assigments can be anything you like. It is often helpful to use variables that will remind you what they stand for. Here, we have chosen A = amount (final balance); P = principal (initial investment); r = rate.
The three integers are 5,17 and -10
Step-by-step explanation:
Let x, y and z be three integers then
'The sum of the first and second integers exceeds the third by 32'
The third integer is 15 less than the first.
From Eqn 2:
Subtracting Eqn 1 from eqn 2
Dividing both sides by -2
Putting z=-10 in Eqn 3
Putting x=5 and z=-10 in Eqn 1
Hence,
The three integers are 5,17 and -10

Answer: vertical line.
Step-by-step explanation:
Ok we can define a function f(x) as "something" that maps a given input (we usually call the input "x") into a given output (we usually call the output "y")
We have one rule for functions, each input can be mapped into only one output.
So if for example, for a given value x = A.
f(A) = B
and
f(A) = C
This is mapping the input A into two different outputs, then this is not a function.
Now to the question.
If we have a vertical line (parallel to the y-axis)
This line will have only one value of x associated with it, but all the values of y.
This means that this maps one value of the input into infinite outputs, then this can not be a function.
