Romashka-Z-Leto [24]2 years ago
3 0

Answer:

X = 45

Step-by-step explanation:

90 + X + A = 180 (angles of a triangle sum to 180)

90 + X + 45 = 180

X = 45

Answer, please. Thanks in advance
myrzilka [38]

Answer:

y = -2/4x + 2 --- SLOPE INTERCEPT FORM

OR IF WANTING IT TO BE SIMPLIFIED:

y = -1/2x + 2 --- SLOPE INTERCEPT FORM

Step-by-step explanation:

The starting point is 2. The slope is -2/4 or if it needs to be simplified, then it's -1/2.


Sorry if I'm incorrect...

In what form can a linear equation in x and y be written in?
Sati [7]

Answer:

Slope-Intercept Form of a Line (y = mx + b)

Step-by-step explanation:

The slope-intercept is the most “popular” form of a straight line. Many students find this useful because of its simplicity. One can easily describe the characteristics of the straight line even without seeing its graph because the slope and y-intercept can easily be identified or read off from this form.

Write the equation of the trigonometric graph.
prisoha [69]

Answer:

f(x)= \sin(6x)+3

Step-by-step explanation:

The parent function of this graph is:  y = sin(x)

The sine function is periodic, meaning it repeats forever.

Standard form of a sine function:

f(x) = \sf A \sin (B(x + C)) + D

  • A = amplitude (height from the mid-line to the peak)
  • 2π/B = period (horizontal distance between consecutive peaks)
  • C = phase shift (horizontal shift - positive is to the left)
  • D = vertical shift

The parent function y = sin(x) has the following:

  • Amplitude (A) = 1
  • Period = 2π
  • Phase shift (C) = 0
  • Vertical shift (D) = 0
  • Mid-line:  y = 0

From inspection of the given graph:

  • Amplitude (A) = 1
  • \sf Period=\dfrac{\pi}{12}-\dfrac{-\pi}{4}=\dfrac{\pi}{3}
  • Phase shift (C) = 0
  • Vertical shift (D) = +3  (as mid-line is y = 3)

\sf If\:Period=\dfrac{\pi}{3} \implies \dfrac{2 \pi}{B}=\dfrac{\pi}{3}\implies B=6

Substituting the values into the standard form:

\implies f(x) =1 \sin (6(x + 0)) + 3

\implies f(x) = \sin (6x) + 3

Therefore, the equation of the given trigonometric graph is:

f(x)= \sin(6x)+3
