How do you do equations and equalities on a number line

Mathematics

castortr0y [4]3 years ago

To graph an equation on a number line, You place a point at where the number lies. For example, x=5 would mean that you place a point on 5 and not draw a line.

To graph an inequality on a number line, if depends if it is <, >, ≤, or ≥ . If it is ≤, it is a closed point on the number and a line moving to the left of the number. If it is a ≥, then it is a closed point on the number with a continuous line to the right. If it is a <, it is an open point on the number with a line going to the left. If it is a >, then it is an open point going to the right.

I'll attach a photo to show you what it looks like! :) Hope this helps! :)

I was doing my homework and got confused on this question.
spayn [35]

We will determine the length of the segment DF as follows:

*We have that the triangles are similar, and therefore the following is true:

\frac{2}{1.34}=\frac{4}{DF}

Now, we solve for DF:

\Rightarrow DF=\frac{1.34\cdot4}{2}\Rightarrow DF=2.68

From this, we have that the length of the segment DF equals 2.68 units.

Solve using algebraic equation: <br> 5sin2x=3cosx
disa [49]
\bf 5sin(2x)=3cos(x)\qquad \qquad  sin(2\theta)=2sin(\theta)cos(\theta)\qquad thus&#10;\\\\&#10;5[2sin(x)cos(x)]=3cos(x)\implies 10sin(x)cos(x)=3cos(x)&#10;\\\\&#10;10sin(x)cos(x)-3cos(x)=0\impliedby \textit{taking common factor}&#10;\\\\\\&#10;cos(x)[10sin(x)-3]=0\implies &#10;\begin{cases}&#10;cos(x)=0\to &\measuredangle x=cos^{-1}(0)&#10;\\\\&#10;sin(x)=\frac{3}{10}\to &\measuredangle x = sin^{-1}\left( \frac{3}{10} \right)&#10;\end{cases}
