Answer:

The slope of red line is $-\dfrac{1}{2}$

B is correct.

Step-by-step explanation:

Two lines are parallel. Two lines shown by color green and red line.

As we know if lines are parallel then their slope is equal.

W are given green line is parallel to red line.

The slope of green line is $-\dfrac{1}{2}$

But The slope of red line = slope of green line.

Slope of red line $=-\dfrac{1}{2}$

Hence, The slope of red line is $-\dfrac{1}{2}$

Answer:

The function f has an inverse because it is one-to-one.

Step-by-step explanation:

The condition for a function to have an inverse is that every x coordinate maps to a single y - coordinate. As illustrated by the diagram attached in the second picture, every x value maps to one y value therefore satisfying the condition making the function have an inverse.

What is the slope of this line? <br> The coordinates are: (-4,5),(0,6), and (8,8).

Elodia [21]

Answer:

Step-by-step explanation:

we have to use the formula of slope here.

we know,

slope of the line passing through (x1,y1) and (x2,y2) is-

$\frac{y2-y1}{x2-x1}$

Here, the first two points are -

(-4 , 5) and (0,6)

So, the slope will be-

$\frac{6-5}{0-(-4)}=\frac{1}{0+4}=\frac{1}{4}$

So, the slope is-

$\frac{1}{4}$

Answer:

Pedro pagó $448

Step-by-step explanation:

Sea P el precio inicial de un objeto.

Si aplicamos un descuento del X%, entonces el nuevo precio del objeto es:

NP = P*(1 - X%/100%)

y lo que estamos ahorrando es:

P - NP

En este caso, primero tenemos un descuento del 30%, entonces:

NP = P*(1 - 30%/100%) = P*(1 - 0.3)

Luego tenemos otro descuento, esta vez del 20%, entonces:

NP' = NP*(1 - 20%/100%) = P*(1 - 0.3)*(1 - 20%/100%) = P*(1 - 0.3)*(1 - 0.2)

Lo que Pedro ahorra es igual a $352

entonces:

P - NP' = $352

P - P*(1 - 0.3)*(1 - 0.2) = $352

P*(1 - (1 - 0.3)*(1 - 0.2)) = $352

P*(1 - 0.56) = $352

P = $352/(1 - 0.56) = $800

Esto significa que el precio original era $800.

Y lo que pedro pago esta dado por la ecuación:

NP' = P*(1 - 0.2)*(1 - 0.3) = $800*(1 - 0.2)*(1 - 0.3) = $448.
