C. both a relation and a function
2. We have 25+15+10=50 minutes total work out, 25 lifting, so a ratio of
25:50 which is simplified to
Answer: 1:2
3.

so here
ratio of mixture is actually ratio of number of pints
so
blue pints/ red pints = b/r =2/5
so
b = (2/5) r
b = (0.4) r
Question 9.)
5-2(5)-1
10-1
Y=9
(X,Y) = 5,9
2- 2(2)-1
4-1
Y=3
(X,Y)= 2,3
0- 2(0)-1
2-1
Y=1
(X,Y)= 0,1
10)
4- 3(4)-7
12-7
Y=5
(X,Y)=4,3
1- 3(1)-7
3-7
Y=-4
(X,Y)= 1,-4
0- 3(0)-7
0-7
Y=-7
(X,Y)= 0,-7
(I believe you are supposed to plot the (X,Y) points on the graph)
Isolate m using inverse operations, get m by itself. (addition and subtraction, mult. and div.)
