Which of the following absolute value equations has no solutions?Group of answer choices

Amiraneli [1.4K]

The absolute value measures the distance a number is away from the origin (zero) on the number line. A number can be to the left or right of zero on the number line, but the distance away from zero is always positive. Graphically:

In other words:

• If d is positive and

$\begin{gathered} |x|=d \\ \text{ then} \\ x=d\text{ or }x=-d \end{gathered}$

• If d is negative and

$\begin{gathered} |x|=-d \\ \text{then} \\ \text{ No solution, because distance (d) can not be negative.} \end{gathered}$

Therefore, the equation that has no solutions is:

$\boldsymbol{|x|=-3}$

Write an algebraic expression which represents the volume of a cylinder whose radius is 3k and height is 2k + 1.

pickupchik [31]

V=hπr^2

V=(2k+1)π(3k)^2

V=π(2k+1)(9k^2)

V=π(18k^3+9k^2)

V=18πk^3+9πk^2
