C. 4/7
Parallel lines have the same slope, so u must find the slope of line a
To find the slope you take two points and use the formula (y2-y1)/x2-x1
The two points given are (-7,0) and (0,4)
To figure it out fill in the formula with the points
Slope= 4-0/0-(-7)
=4/7
1 is PQR and RQP
2 is ABC and CBA
3 is STU and UTS
It is 9/12 and simplified that is 3/4
D. 40
follow the pattern
1 band director calls 3 members. = 4
Each member calls 3 more members 3(3) = 9
Then each of those 9 call 3 more members 9(3) = 27
Add them up
4+9+27 = 40
You would have to get 3 ounces of seeds and 7 ounces of dried fruit for price per ounce of the mix would be 2.20
