Explanation:
Find the Derivate -10/x
=10/x^2
Plug in -12 for x
10/(-12)^2
=5/72
The equation to solve this would be:
-4+x=25
Solve for x.
Add 4 to both sides.
(-4+x)+4=(25)+4
x=29
The overall change to account was $29.
Hope this helps.

Answer:
x = -1
Step-by-step explanation:
5x + 3y = 26
- (6x + 7y = 21)
_________
-x - 4x = 5
-5x = 5
x = -1
X ≥ -3
y ≥ 5x - 9
3x + y ≤ 15
3(-3) + (5x - 9) ≤ 15
-9 + (5x - 9) ≤ 15
(-9 - 9) + 5x ≤ 15
-18 + 5x ≤ 15
<u>+ 18 + 18</u>
<u>5x</u> ≤ <u>33</u>
5 5
x ≤ 6.6
y ≤ 5(6.6) - 9
y ≤ 33 - 9
y ≤ 24
(x, y) ≤ (6.6, 24)
