3 0

Answer:

x = 100√3


Step-by-step explanation:

tan(30º) = x/300

x = 300 tan(30º)

x = 300/√3

x = 100√3

State the equation of the line<br> that is perpendicular to 4x-3y=10<br> through the point (-2,4)
Lynna [10]

The equation of the line  that is perpendicular to 4x - 3y = 10  through the point (-2,4) is y-4=\frac{-3}{4}(x+2)

<u>Solution:</u>

Given, line equation is 4x – 3y = 10  

We have to find a line that is perpendicular to 4x – 3y = 10 and passing through (-2, 4)

Now, let us find the slope of the given line,  

\text { Slope of a line }=\frac{-\mathrm{x} \text { coefficient }}{\mathrm{y} \text { coefficient }}=\frac{-4}{-3}=\frac{4}{3}

We know that, slope of a line \times slope of perpendicular line = -1

\begin{array}{l}{\text { Then, } \frac{4}{3} \times \text { slope of perpendicular line }=-1} \\\\ {\rightarrow \text { slope of perpendicular line }=-1 \times \frac{3}{4}=-\frac{3}{4}}\end{array}

Now, slope of our required line = \frac{-3}{4} and it passes through (-2, 4)

<em><u>The point slope form is given as:</u></em>

\begin{array}{l}{y-y_{1}=m\left(x-x_{1}\right) \text { where } m \text { is slope and }\left(x_{1}, y_{1}\right) \text { is point on the line. }} \\\\ {\text { Here in our problem, } m=-\frac{3}{4}, \text { and }\left(x_{1}, y_{1}\right)=(-2,4)} \\\\ {\text { Then, line equation } \rightarrow y-4=-\frac{3}{4}(x-(-2))}\end{array}

y-4=\frac{-3}{4}(x+2)

Hence the equation of line is found out

Write the equation of the line in slope-intercept form that passes through
never [62]

Answer:

y= -2/3x+3

Step-by-step explanation:

Parallel lines have the same slope but different y-intercepts.

y=-2/3x is your original equation

Your slope is still -2/3

y=mx+b

y=-2/3x + b

Substitute the points from the coordinates

5 = -2/3(-3) + b

5 = 2 + b

-2   -2

b=3

Your parallel line equation is: y= -2/3x+3

Have a great day!

Complete the equation and tell which property you used. (3×10)×8=___(10×8)
just olya [345]
To complete the equation and tell which property you used. (3×10)×8=___(10×8)
The property of basic operations that was used here is the:
1. Associative property of multiplication where you can group or cluster certain values or numbers in an equation and still yield the same product.

The missing value would be 3. Hence,
2. (3 × 10) × 8 = 3 (10 × 8) Observe the parenthesis which has only moved from starting with three to the value of ten.
