Write the solution to the given inequality in interval notation.
vladimir2022 [97]

Option D: (-\infty, 0) is the solution to the inequality in interval notation.

Explanation:

The number line shows the interval of numbers starting from 0 and goes on.

From the number line, it is obvious that the open circle at the point 0 indicates that we don't want to include the number 0.

Hence, in interval notation, we can write that the end values not to be included can be written with a round bracket ( )

Thus, the interval can be written as (-\infty, 0)

Hence, the solution to the inequality in interval notation is (-\infty, 0)

Therefore, Option D is the correct answer.

Step-by-step explanation:

First lets do look at it without the absolute value marks

4x-1=13

4x=14

x=7/2

In ΔJKL, k = 3.7 cm, ∠K=15° and ∠L=41°. Find the length of j, to the nearest 10th of a centimeter.
Alexandra [31]

Answer:

The length of side j is 11.85cm

Step-by-step explanation:

Given that

In triangle JKL,

\angle k=15

\angle l=41

Side k=LJ=3.7cm

To find side j=KL:

By using sine rule,

We can write as

\frac{SinK}{LJ} = \frac{SinL}{JK} = \frac{SinJ}{KL} \\\frac{Sin15}{3.7} = \frac{Sin41}{JK} = \frac{SinJ}{KL}

Using property of triangle,

\angle k+\angle l+\angle j=180

15+41+\angle j=180

\angle j=124

\frac{Sin15}{3.7} = \frac{Sin41}{JK} = \frac{Sin124}{KL}\\\frac{Sin15}{3.7} = \frac{Sin124}{KL}\\KL=3.7\frac{Sin124}{Sin15}\\KL=3.7\frac{0.8290}{0.2588}\\KL=11.85cm

Thus,

The length of side j is 11.85cm
