Solve –|2x+3|=1 for x it might have more than one answer

1 answer:

3 0

There is no answer.

Logically speaking, absolute value returns an output that is zero or positive.

Rearranging the equation gives:
|2x + 3| = -1

No matter what we substitute, we cannot get a negative number after applying the absolute value.

Therefore, the expression is undefined.

If a sample of 99 bowlers were taken from a population of 466 bowlers,x could refer to the mean of how many bowlers scores

otez555 [7]

Answer:

x is a mean of 99 bowlers scores

Step-by-step explanation:

Sample mean x is the mean of data samples taken from a population.

x is the sample mean

Number of population = 466

Number of samples = 99

Since, x is the mean of data samples, then x is the mean of the 99 sample data taken.

Therefore, x is a mean of 99 bowlers scores.

Use the given information to find the unknown value:y varies inversely with a. When x = 4, then y= 4. Find y when I = 2.Iyy =hel

Mashutka [201]

Inverse variation:

$y=\frac{k}{x}$

k is a constant

Use the given information (when x=4 y=4) to find the value of the constant:

$\begin{gathered} 4=\frac{k}{4} \\ \\ \text{Multiply both sides of the equation by 4:} \\ 4\times4=4\times\frac{k}{4} \\ \\ 16=k \\ \\ \\ k=16 \end{gathered}$

Then, the given relationship has the next equation:
