X=6.75

3+x=5x-24 Add 24 on both sides
27+x=5x Subtract 1x on both sides
27=4x Divide 4 on both sides
6.75=x You Can double check by plugging in x

If f\left(x\right)=\mid x\midf ( x ) =∣ x ∣, then what is the new function g\left(x\right)g ( x ) when f\left(x\right)f ( x ) is

Leni [432]

Answer:

$g(x) = 2 (|x| - 3)$

Step-by-step explanation:

Given

$f\left(x\right)=\mid x\mid$

Translation = 3 units down

Vertical stretch of 2 to give g(x)

Required

$g\left(x\right)$

3 units down translation

A function is translated down as follows:

$h(x) = f(x) - k$

Where k is the number of units.

So:

$h(x) = f(x) - k$

$h(x) = |x| - 3$

Vertical stretch of 2

A function is vertically stretched as follows;

$g(x) = ah(x)$

Where a is the units stretched.

In this case:

$a = 2$

So:

$g(x) = ah(x)$

$g(x) = 2 * (|x| - 3)$

$g(x) = 2 (|x| - 3)$

14. A plane traveled from California and back. It took one hour longer on the way out than it did on the way back. The plane's a

kow [346]

Answer:

C. 7 hours

Step-by-step explanation:

Let the time for the trip out be represented by t. Then the time for the return trip is t-1. The distance was the same for both trips, so we have ...

distance = speed × time

300t = 350(t -1)

300t = 350t -350 . . . . eliminate parentheses

350 = 50t . . . . . . . . . . add 350-300t

7 = t . . . . . . divide by 50

The trip out took 7 hours.
