Answer:
f(4) = -1
Step-by-step explanation:
To find the function, or f, of x given a point, plug in the value of x for x in f(x). Then, find the corresponding y-value. The function of 4 is -1 in this example, so the final result looks like f(4) = -1.
Answer: y = 0.4x
In fraction form, this is y = (2/5)x
================================================
Explanation:
For each row, divide the y over x values
- Row One: y/x = 0.8/2 = 0.4
- Row Two: y/x = 4/10 = 0.4
- Row Three: y/x = 6/15 = 0.4
- Row Four: y/x = 10/25 = 0.4
We end up with the same thing each time.
Since y/x = 0.4, this rearranges to y = 0.4x
Alternatively, you can write the equation as y = (2/5)x because 2/5 = 0.4
This would be a question that would involve division.
We do: (1,600 ÷ 4) and therefore, this would give us
just as we were looking for, and therefore,
B would be your correct answer.
Answer:
835.865333
Step-by-step explanation:
16.6×16.6=275.56
275.56×9.1=2507.596
2507.596÷3=835.865333
Answer
The equation simplified is: r=x+1
