Answer: B) (-x, y)

Step-by-step explanation:

If a coordinate is reflected across the y-axis, the y-coordinate stays the same but the x-coordinate changes signs.

Consider (1, 2) as the original point. Now reflect it across the y-axis. The new coordinate is (-1, 2). The y-coordinate stayed the same (2) but the x-coordinate changed signs (1 → -1).

a theatre contains 431 seats and the ticket prices for a record play were $53 for adults and $24 for children. if the total proc

Nataly_w [17]

X = adult
y = children

53(x+y=431)
53x +24y = 15390$

53x+53y = 22,843
subtract from
53x+24y = 15,390

29y = 7,453$
y = 257

53x + 24 (257) = 15,390
53x + 6,168 = 15,390
53x = 9,222
x = 174

Are the functions linearly dependent on the interval (0,1)? y1=sintcost,y2=4sin2ty1=sin⁡tcos⁡t,y2=4sin⁡2t hint: recall that func

VikaD [51]

Answer: hello your question is poorly written attached below is the complete question

answer:

since y1 = 1/2 y2 on ( 0,1 ) the function are linearly dependent on ( 0,1 ) ( B )

Step-by-step explanation:

First step : Determine if y1 and y2 are linearly dependent

interval = ( 0,1 )

Functions: y1 = sin t cost t , y2 = 4 sin t

We can verify if these functions are linearly independent or linearly dependent by using the determinate form

attached below is the detailed solution

From the attached solution we can conclude that

y1, y2 is linearly dependent on ( 0,1 )

hence ; since y1 = 1/2 y2 on ( 0,1 ) the function are linearly dependent on ( 0,1 )
