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
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 = 
<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)].

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!
