It is not reasonable because 1365 is no where near 10,000, so a reasonable estimate is over 1,000 pounds
This question is the usual way to do this problem. Just multiply the 4 by 2 so that you have 3*? / 4 * 2 .
What you do to the top part of the fraction is what you do to the bottom part.
3*2 / 4 * 2 = 6 / 8
So the answer is 6 / 8
The answer should be 31
(10(3)+8)-(1(3)+4)
(30+8)-(3+4)
= 31
-8x+9y=23 -- y=8/9x+23/9
(-4,-1), (1/2,3)
(3--1)/(1/2--4)= 4/(4 1/2)=.888888889
So answer A because if you rearrange it in y=mx+b form you see it's y=8/9x+23/9. And using the two points provided you can subtract to find the slope which comes out to be 8/9 the only two answers with that are A and B, so eliminate C and D. Then you can easily tell by looking at the graph that the y-intercept is positive, thus answer A is the only answer that works.
