Perpendicular means that it has a slope that is the reciprocal of the original, and parallel means that the slopes are the same.

Tip:

With these kinds of equations focus on the x and y values

Same exact values = parallel

x and y values are swapped = perpendicular

anything else = neither

Answer:

$D.\ y = 3\sin(2(x + \frac{\pi}{4}))$

Step-by-step explanation:

Given

$A = 3$ --- Amplitude

$C = \frac{\pi}{4}$ --- Right phase shift

Required

Identify the function

A sinusoidal function is defined as:

$y = A\sin(B(x + C)) + D$

Substitute values for A and C

$y = 3\sin(B(x + \frac{\pi}{4})) + D$

By comparison, only option (D) has the above format where

$y = 3\sin(2(x + \frac{\pi}{4}))$

Hence (D) is correct

How to write a slope equation using y intercept as 6 and the slope as -2

Bingel [31]

The slope equation is y=mx+b where m is the slope and b is the y intercept. After plugging the numbers into the equation you should get y=-2x+6. Hope this helps!

A taxi driver charges a fixed rate of $2 and he charges $19.50 for a 7-mile trip

KiRa [710]

You will pay $2.78 per mile for a total of 7 miles you will pay $19.50, but you must remember the taxi driver charges a $2.00 fixed rate so your final total will be $21.50
