Answer:
B) 3:4
Step-by-step explanation:
since (p,r) lies on y=x+b , it will satisfy the equation
=> r = p + b ......(1)
also, (2p,5r) lies of y=2x+b,it will satisfy the equation
=> 5r = 4p + b .....(2)
Subtracting (1) from (2),we get
4r=3p
Therefore,r:p=3:4
Answer: This question is not right
Step-by-step explanation:
What you have asked is how much should the numbers go up on a graph so it all fits on the graph and can be understood.
1st we need to know what data if your numbers were 5 15 20 25 25 20 15 an appropriate interval would be by 5's however if your data was 100 500 1100 800
There would be no way you could fit it on a graph if you went up by five. A better interval would be 100's
Based on my response I hope you can see that in order to find appropriate interval to graph the data we need the data and that you now see what to do or can update the question
Answer:45 ?
Step-by-step explanation:
Direct variation means y=kx (inverse variation is yx=k or y=k/x)
so we are given that:
75=k/2, so k=150 which means:
y=150x now
y(2.25)=150(2.25)=337.5
