What is an equation of the line that passes through the points (-4, -1)(−4,−1) and (6, -1)(6,−1)?

Vlada [557]

$\boxed{y=-1}$

<h2>Explanation:</h2>

In order to solve this problem, let's remember the point-slope form of the equation of a line:

$y-y_{1}=m(x-x_{1}) \\ \\ m:slope \\ \\ (x_{1},y_{1}):A \ point \ on \ the \ line$

We know two points:

$(x_{1},y_{1})=(-4, -1) \\ \\ (x_{2},y_{2})=(6, -1)$

So:

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} \\ \\ m=\frac{-1-(-1)}{6-(-4)} \\ \\ m=0$

So this is a constant line (slope equals zero). Therefore, every point has a y-coordinate $y=-1$ . In other words, the equation is:

$\boxed{y=-1}$

Si "m" es el lado mayor de un triángulo, dos cuyos ángulos interiores miden 30° y 60°, entonces el perímetro del triángulo es

lions [1.4K]

Answer:

$perimetro = \dfrac{(3 + \sqrt{3})m}{2}$

Step-by-step explanation:

triángulo 30°-60°-90°

$1~:~\sqrt{3}~:~2$

$1m~:~m\sqrt{3}~:~2m$

$\dfrac{m}{2}~:~\dfrac{m\sqrt{3}}{2}~:~m$

$perimetro = \dfrac{m}{2} + \dfrac{m\sqrt{3}}{2} + m$

$perimetro = \dfrac{m}{2} + \dfrac{m\sqrt{3}}{2} + \dfrac{2m}{2}$

$perimetro = \dfrac{m + m\sqrt{3} + 2m}{2}$

$perimetro = \dfrac{3m + m\sqrt{3}}{2}$

$perimetro = \dfrac{(3 + \sqrt{3})m}{2}$

If a 25 ft rope is cut into two sections with one section 4 times as long as the other section, how long is the shorter piece?

DaniilM [7]

X = short section of rope
4x = longer section of rope

x + 4x = 25
5x = 25
x = 5

…or in other words the shorter piece of rope is 5 feet long
