Hi there!

$\large\boxed{f(-6) = 5}$

The value of f(-6) is the y-value at the x-coordinate x = -6.

Looking at the graph, we can see that at x = -6, y = 5.

Therefore, f(-6) = 5.

7. What is the slope of the line that passes through the points (14, -18) and (5, -12)?

worty [1.4K]

Answer:

slope = $-\frac{2}{3}$

Step-by-step explanation:

Use the slope formula $m = \frac{y_2-y_1}{x_2-x_1}$ to find the slope, or $m$ . The $x_1$ and $y_1$ represent the x and y values of one point, and the $x_2$ and $y_2$ represent the x and y values of another point. So, substitute the x and y values of the points (14, -18) and (5, -12) into the formula and solve:

$m = \frac{(-12)-(-18)}{(5)-(14)}\\m = \frac{-12+18}{5-14}\\m = \frac{6}{-9} \\m = -\frac{2}{3}$

Thus, the slope is $-\frac{2}{3}$ .

A company manufactures and sells video games. A survey of video game stores indicated that at a price of $66 each, the demand wo

AysviL [449]

Answer:

$y=-30x+2380$

Step-by-step explanation:

$x\rightarrow$ represent price per video game.

$y\rightarrow$ represent demand.

The linear equation in slope intercept form can be represented as:

$y=mx+b$

where $m$ is slope of line or rate of change of demand of game per dollar change in price and $b$ is the y-intercept or initial price of game.

We can construct two points using the data given.

When price was $66 each demand was 400. $(66,400)$

When price was $36 each demand was 1300. $(36,1300)$

Using the points we can find slope $m$ of line.

$m=\frac{y_2-y_1}{x_2-x_1}$

$m=\frac{1300-400}{36-66)}$

$m=\frac{900}{-30}$

$m=-30$

Using point slope form of linear equation to write the equation using a given point.

$y-y_1=m(x-x_1)$

Using point $(66,400)$ .

$y-400=-30(x-66)$

⇒ $y-400=-30x+1980$ [Using distribution]

Adding 400 to both sides:

⇒ $y-400+400=-30x+1980+400$

⇒ $y=-30x+2380$

The linear relationship between price and demand can be written as:

$y=-30x+2380$

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°

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

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

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

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

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

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

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

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