Which of the following is the solution to 3I x-1 I≥ 12?
1 answer:
The solution for the given inequality will be x≤ -3 or x≥ 5. Thus, the correct option is B.
<h3>What are inequalities?</h3>Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed. It is mostly denoted by the symbol <, >, ≤, and ≥.
For the given inequality the solution can be found as,
- When the value of x is negative,
3|x-1| ≥ 12
x-1 ≥ 4
x ≥ 5
- When the value of x is positive,
3|x-1| ≥ 12
- x + 1 ≥ 4
-x ≥ 3
x ≤ -3
Hence, the solution for the given inequality will be x≤ -3 or x≥ 5. Thus, the correct option is B.

The domain is the set of all numbers. The range is also the set of all real numbers.
Why is this the case? Because the line extends forever in both directions along the x and y axis. We can plug in any x value and solve for y, or vice versa, and we don't have any restrictions for the input or output.

To write "the set of all real numbers" in interval notation, you would write
This is the interval from negative infinity to positive infinity, spanning the entire real number line.
A
given that y varies directly as x, then the relationship is
y = kx ← k is the constant of variation
To find k use the given condition x = 3 when y = 24
y = kx ⇒ k = =
= 8
y = 8x
