Step-by-step explanation:
a. the domain ={-3, 0, 1, 2}
the range = {6, 2, 0, -3}
the relation is a function
b. the domain = {-1, 2, 1}
the range = { -4, 8, 4}
the relation is not a function
Answer:
15 feet
1. 3x-9+2y
2. 7x+6
1. 2x + (x - 4) + (2y - 5)
2x+x-4+2y-5
3x-9+2y
2. 3(x - 2) + 4(x + 3)
3x+4x-6+12
7x+6
White: 28 Blue: 20 Red: 32
Step-by-step explanation: Make ratios. If 35% are White strands then it would be 35/100 = ?/80 you can use the butterfly method to solve this:
35*80 = ?*100
? = 28
Blue: 25/100 = ?/80
(you can use the butterfly method or you can simplify 25/100 into 1/4)
1/4 = ?/80
1*80 = ?*4
? = 20
Red: 40/100 = ?/80 (once again, you can simplify if you want)
4/10 = ?/80
4*80 = ?*80
? = 32
