Answer:
The answer is c. f(n)=4n+1
Step-by-step explanation:
In the function of the answers, n is the input and f(n) is the output. So the ordered pairs needs to be at the form (n,f(n))
Additionally, in the ordered pairs given in the question, the first term is the input and the second term is the output. For example in the ordered pair (1,5), 1 is the input and 5 is the output.
So, if we replace n by 1, f(n) needs to be 5. This condition is only satisfied on option c. That's is also prove for every ordered pair as:
For (1,5)
if n=1 then:
f(n)=(4*1)+1=5
For (2,9)
if n=2 then:
f(n)=(4*2)+1=9
For (3,13)
if n=3 then:
f(n)=(4*3)+1=13
For (4,17)
if n=4 then:
f(n)=(4*4)+1=17
Finally, the functions that best represents the rule that the calculator uses to display the outputs is f(n)=4n+1
Answer:
Answer
Step-by-step explanation:
OK, there are 360 students in the whole school and 15 classes there, too.
Each class has an EVEN amount of students, so simply, all you need to do is divide (360 divided by 15)
I believe it A because it on the negative side of the graph
Answer:
As we know:
Direct variation => y = k*x, k is constant ( y/x = k = constant)
Inverse variation => y = k/x, k is constant (y*x = k = constant)
X - 1 2 5 10
Y - 6 12 30 60
Check the first 2 pair of X, Y:
(the remaining pair of value would show the same tendency)
X1 x Y1 = 1 x 6 = 6
X2 x Y2 = 2 x 12 = 24
=> X x Y is not a constant
=> Not an inverse variation.
=> B and D is incorrect
Otherwise, we have:
Y1/X1 = 6/1 = 6
Y2/X2 = 12/2 = 6
=> Y/X = 6
=> A direct variation with k = 6
=> y = 6x
=> Option C is correct
