en dos líneas paralelas cortadas por una trasversal el valor de un ángulo es 2×-14 y su suplementario mide 3×-18​
ASHA 777 [7]

Responder:

x = 42,4

Explicación paso a paso:

Podemos encontrar el valor de x ya que no se nos dice qué buscar

La suma de dos ángulos suplementarios es 180 grados, por lo tanto;

2x - 14 + 3x - 18 = 180

2x + 3x - 32 = 180

5 veces = 180 + 32

5 veces = 212

x = 212/5

x = 42,4

Por tanto, el valor de x es 42,4

Cant remember how to do this :( Please help !!​

Answer:

B

Step-by-step explanation:

1) Look at the y-intercepts.

The y-intercepts on both equations are the same: 5. That means both equations touch the y-axis at (0,5).

That means we can rule out both A & C.

2) Calculate the rate of change (a.k.a. slope) of f(x).

To do this, we must use two points to find the change of y over the change of x. From the graph, we can use the points (1,2) and (2,-1).

Δy / Δx = \frac{-1 - (2)}{2-1} = \frac{-3}{1} = -3

<em>*The little triangles are the Greek symbol delta. They mean change in...*</em>

That means that the slope of f(x) is -3.

3) Figure out the rate of change (a.k.a. slope) of g(x).

To do this, all we have to do is look at the equation. It is written in y = mx + b format where m = slope and b = y-intercept. That means the slope is 5 as in place of "m" there is a 5.

4) The Answer

The answer is B because 5 [the rate of change for g(x)] is greater than -3 [the rate of change for f(x)].

Express as a trinomial.<br> (3x – 1)(3x – 8)
mote1985 [20]

Answer:

9x² - 27x + 8

Step-by-step explanation:

You would use the "FOIL" method, which stands for First, Outside, Inside, Last. Honestly, I don't keep that in mind specifically, but I use the method.

I look at this like distributing the first term to the last two, then adding what you get from distributing the second term with the last two.

(3x – 1)(3x – 8)

= (9x² - 24x) + (-3x + 8)

= 9x² - 27x + 8

Eventually, you won't have to write out the entire process since it's basic multiplication.

I hope this helps!
