Answer:
B. 11.85% = 12%
Step-by-step explanation:
500 * .10 + 300 * .15 = 50 + 45 = 95.
95/800 = .11875
.11875 = 11.875%
Answer:
It is a linear function because the degree is 1. The function is also neither odd nor even.

Answer:
- perimeter ratio: 4 : 3
- area ratio: 16 : 9
Step-by-step explanation:
The ratio of perimeters is the ratio of corresponding sides.
first : second = 8 : 6 = 4 : 3 . . . ratio of perimeters
The ratio of areas is the square of the ratio of linear dimensions.
first : second = 4² : 3² = 16 : 9 . . . ratio of areas
<span>2(3 - x) = -16
3 - x = -16/2
3 - x = -8
-x = -8 - 3
-x = - 11
x = 11</span>
