I think that your answer would be 3 and 2.

Explanation: A coefficient is a number used to multiply a variable. The variables are x and r. 3 is being multiplied by x, and 2 is being multiplied by r.

I hope this helped! Mark as brainliest if you don’t mind ;)

Through: (3, 5) parallel to y=3x-1
marysya [2.9K]

Answer:  y = 3x - 4  will be the parallel line to the line  y= 3x -1

Step-by-step explanation:

Parallel lines have the same slope but different y intercepts, so using the equation given , use the formula y=mx +b  where m is the slope and b is the

y - intercept ,and input the x and y coordinate to solve for b. Input the same slope into the formula because they will have the same slope.

 5= 3(3) + b  

5 =  9  + b

-9    -9

b = -4    

Since the y intercept is negative 4, the equation will be  y = 3x -4

Dada la función f(x)=1+6Sen(2x+π/3) . Halle: Período, amplitud y desfase (1.5 puntos) Dominio y rango de la función (1.5 puntos)
Liula [17]

Dada una ecuación de la forma

<h3>y = A sin(B(x + C)) + D</h3>

Tenemos que:

  • la amplitud es A
  • el periodo es 2π/B
  • el desfase es C (a la izquierda es positivo)
  • el desplazamiento vertical es D

Sabemos que:

f(x)=1+6Sen(2x+π/3)

Y podemos reescribirla como:

f(x)=6Sen(2(x+π/6))+1

Siendo:

  • A = 6 → Amplitud
  • T = 2π/B = 2π/2 = π → Período
  • C = π/6 → Desfase
  • El dominio de un a función trigonométrica es todo el conjunto de los números reales (x ∈ R ).

La imagen de una función trigonométrica de esta forma es:

y ∈ [-A+D,A+D]

y ∈ [-6+1, 6+1]

y ∈ [-5,7]
