12 and any number higher than 12 solves this inequality.
Breakdown: The inequality is saying y subtract 6 is greater than or equal to 12. Any number less than 12 will not satisfy this.

L(x) = f'(a)(x - a)
f(x) = x^(-1), f'(x) = -x^(-2)
Let a = 1, f'(a) = -(1)^(-2) = -1
L(0.9) = f'(1)(0.9 - 1) = -1(-0.1) = 0.1
Therefore, linear approximation of f(x) = x^(-1) for x = 0.9 is 0.1
Answer:
x = 4
y = 13
Step-by-step explanation:
x + y = 17
y = 2x + 5
substitute for y:
x + (2x + 5) = 17
reduce:
3x + 5 = 17
subtract 5 from each side:
3x = 12
divide both sides by 3:
x = 4
y = 2(4) + 5
y = 13

The perimeter of a square is 52 m. What is the area of the square ?
<h2><u>S</u><u>o</u><u>l</u><u>u</u><u>t</u><u>i</u><u>o</u><u>n</u>:-</h2>
Perimeter of a square = 52 m
4 × side = 52
side =
side = 13
So, area of square = (side)² = (13)² = 169 sq m.
