Describe how the graph of y= x – 12 is like the graph of y= x and how it is different

1 answer:

6 0

The two graphs have the same slope. But the graph of <span>y= x – 12 is 12 units below the graph of y = x. We call that a "vertical translation."

A truck's gas tank holds 50 gallons of gas. if one gallon takes 30 seconds to pump, how many minutes will it take to fill the em

umka2103 [35]

To find how long it will take to fill the tank, you can use the idea that every 30 seconds will get you one gallon closer to being full.

This means to fill 50 gallons, you will need 50 groups of 30 seconds.

50 x 30 = 1500 seconds

1500/60 = 25 minutes.

It will take 25 minutes.

You could also think of it as filling 2 gallons every minute. It would take 25 of these.

-(1/x+3) +4

nlexa [21]

9514 1404 393

Answer:

left 3 units
up 4 units
shape: lower left image

Step-by-step explanation:

For a parent function f(x), the transformations ...

g(x) = a×f(x -h) +k

cause ...

vertical expansion by 'a', reflection over x-axis if negative
right shift by 'h'
up shift by 'k'

Here, we have parent function f(x) = 1/x with a=-1, h=-3, k=4. Then the transformations are ...

horizontal shift left 3 units

vertical shift up 4 units

reflection over x-axis, so curves are above-left and below-right of the reference point (Note that the reflection is done <em>before</em> the translation.)
