You should try both points
put x=5/2 and y=3
5-2=3
the first one is on the graph
put x=3/2 and y=20
3-40/3≠3
the second one is not on the graph
1200 is the domain the answer is times the domain
Answer: B: The range of both f(x) and g(x) is all nonzero real numbers
Step-by-step explanation:
That is the definition of a irrational number, A rational number must be able to be written as a ratio of 2 integers. The denominator cannot be 0, because that would make the number undefined
Answer:
see the explanation below
Step-by-step explanation:
you can type 250 characters in 60 seconds your friend can type 375 characters in 90 seconds do these ratios form a proportion
Given data
you can type 250 characters in 60 seconds
your typing speed = 250/60
= 4.16 characters per seconds
your friend can type 375 characters in 90 seconds
your friends typing speed is
= 375/90
= 4.16 characters per seconds
Since both typing speeds corresponds, hence the ratios are proportional
