Answer: 155y seconds

Step-by-step explanation:

Difference between 3y minutes and 25y seconds is written as

3y minutes- 25y seconds

First, Convert minutes to seconds = 60 seconds makes 1 minute, therefore, 3 minutes = 60 x 3= 180 seconds

Therefore 180y seconds - 25y seconds

= 155y seconds

I hope this helps, please mark as brainliest answer

180y secs-25y secs

Taking y secs common

(180-25) y secs

155 y secs

What transformation of the parent function f(x) is made to get 4f(x+2)

LenKa [72]

Answer: A vertical stretch of 4 and a translation of -2 units in the x-direction.

Step-by-step explanation:

Changes of the parent function can be written, in this case as af(x)(x - k) where a is the stretch factor and k is the movement left or right on the x-axis.

In this case, a = 4 and k = 2. Since the k is negative, the function will be moved -2 units on the x-axis.

Ignore the stuff around it ,could someone explain me this?

Answer:

The lines blue and green are perpendicular

Step-by-step explanation:

we know that

If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is -1)

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

step 1

Find the slope of the blue line

we have the points

(-1,-3) and (0,3)

substitute

$m=\frac{3+3}{0+1}$

$m=\frac{6}{1}=6$

step 2

Find the slope of the red line

we have the points

(3,-3) and (4,2)

substitute

$m=\frac{2+3}{4-3}$

$m=\frac{5}{1}=5$

step 3

Find the slope of the green line

we have the points

(-4,-1) and (2,-2)

substitute

$m=\frac{-2+1}{2+4}$

$m=-\frac{1}{6}$

step 4

Compare the slopes

Blue line ----> $m=6$

Red line ----. $m=5$

Green line ---> $m=-\frac{1}{6}$

The slope of the blue line and the green line are opposite reciprocal ( their product is equal to -1)

therefore

The lines blue and green are perpendicular
