8 White
6 Black
4 Blue
5 Brown
Total=8+6+4+5=23
1. White to brown = 8:5
2. Blue to non-blue =4:(23-4) = 4:19
3. Black to all = 6 : 23
4. Ratios equivalent to Q1, 8:5
Multiply ratio by integer factors:
2(8:5)=16:10
3(8:5)=24:15
4(8:5)=32:20
etc.
Answer:
fg(-2)=f(5×-2+4)=f(-6)=8-10×-6=8+60=68
Answer:
BC ≈ 8.9 units
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos36° = 
= 
= 
( multiply both sides by 11 )
11 × cos36° = BC , then
BC ≈ 8.9 ( to the nearest tenth )
The x values range from -6 to 6, *including* those two numbers, so the domain is [-6, 6], and the y values range from -2 to 2, also inclusively, so the range is [-2, 2]
