An inequality describes a situation in which one quantity is greater than or less than another quantity. Unlike equations, they don't have a specific value as an answer. They show a range of values.
Example:
2x > 10 Divide by 2
When you solve that you'll get 5 and that shows that x is every number that's greater than 5.
Answer:
0.785 m
Step-by-step explanation:
(4-2x)(6-2x)x = Volume
Volume = 4x³ - 20x² + 24x
Max volume: dV/dx = 0
dV/dx = 12x² - 40x + 24 = 0
3x² - 8x + 6 = 0
x = 2.54858377, 0.784749563
Max when d²V/dx² < 0
d²V/dx² = 6x - 8
At x = 0.784749563
6x - 8 = -3.29 < 0
X = Ishaan
y = Christopher
3y = x
x = y + 14 Put the first equation into the second.
3y = y + 14
2y = 14
y = 7
Christopher is 7
Ishaan is 21
