Answer:
6.4 euroes
Step-by-step explanation:
1.20 multiplied by the three parcel =3.6
10 euroes - 3.6 =6.4 euroes
-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.
8x=Length of mississippi river.
x = length of hudson river. (which is 300)
So 300x8=2400 Thus it is 2400 miles long.
