Multiplying both sides of <span>−1/3x≤−6 by -3 results in "x is equal to or greater than 18."
Note that multiplying such an inequality requires reversing the direction of the inequality symbol.
I subst. 18 for x in </span><span>−1/3x≤−6 as a check, and found that the resulting inequality is true.</span>

Answer:
(16 x^8 - x^3 + 6)/(2 x^3)
Step-by-step explanation:
Simplify the following:
(64 x^8 - 4 x^3 + 24)/(8 x^3)
Factor 4 out of 64 x^8 - 4 x^3 + 24:
(4 (16 x^8 - x^3 + 6))/(8 x^3)
4/8 = 4/(4×2) = 1/2:
Answer: (16 x^8 - x^3 + 6)/(2 x^3)
Answer:
b) √200 = 10√2
Step-by-step explanation:
Here, the given expression is: √200
Simplifying the given expression, we get:
200 = 2 x 2 x 2 x 5 x 5
⇒ 200 = (2)² x (5) ² x 2
Taking ROOT both sides, we get:
Hence, √200 = 10√2
Answer:
x^2 - 7x - 1
Step-by-step explanation:
g(x) = x^2– 5x
f(x) = 2x +1
(g - f)(x)
expand to get
gx - fx
Slot in the values
(x^2– 5x) - (2x +1)
expand
x^2 - 5x - 2x - 1
x^2 - 7x - 1
