Answer:
Step-by-step explanation:
Step-by-step explanation:
0.2x² − 0.8x = 1.6
Multiply both sides by 5.
x² − 4x = 8
Complete the square by adding 4 to both sides.
x² − 4x + 4 = 12
(x − 2)² = 12
x − 2 = ±√12
x = 2 ± √12
The positive solution is x = 2 + √12 ≈ 5.46.
Answer:
-3
Step-by-step explanation:
The rate of change is equal to the slope. In this slope intercept form (y=mx+b) m is the slope. Therefore m=-3 and that is the rate of change.
6 - 3 = 3
5/6 - 1/3 = 5/6 - 2/6 = 3/6 = 1/2
answer is : 3 1/2 ( or 7/2)
