Answer:
The autonomous equation refers to a differential equation where the independent variable is absent. In such equations, the information about the location of points of inflection can be obtained by analyzing the second derivative of the equation. Points of inflection occur where the second derivative changes sign. By finding the critical points of the second derivative and determining their nature (whether they are minima, maxima, or points of inflection), we can identify the location of points of inflection.

Combine like terms:6a-2=-16
Add 2 to both sides: 6a=-14
Divide both sides by 6: a=-14/6
Simplify: a=-7/3
6a-2=-16
6a=-14

Step-by-step explanation:
19.65 + 2.35 is exactly 22, not including tax
Answer:
A and C
Step-by-step explanation:
A. 15% off $25
15% = 0.15
0.15 x 25 = 3.75
25 - 3.75 = 21.25
22 or under? Yes
B. 30% off $32
30% = 0.30
0.30 x 32 = 9.60
32 - 9.60 = 22.40
22 or under? No
C. $19.65 plus a 2.35 shipping fee
19.65 + 2.35 = 22
22 or under? Yes
D. $20.45 plus a $1.60 shipping fee
20.45 + 1.60 = 22.05
22 or under? No
Even though this is late, the other answer did not mention A being the answer as well so I hope this helped!

Answer:
The answer is $64.
Step-by-step explanation:
An item regularly priced at $80 is on sale for 20% off.
This amount becomes:
dollars
So, price after discount is dollars
Given is that there is a 3% sales tax.
So, sales tax must have been applied to $64 before final bill.
And we have to tell the sale price before tax, so the answer is $64.
Therefore, the answer is $64.
