The Awnser would be 20.6 rounded up to 21. The final Awnser is 21
The fourth one down is the correct answer trust me
A vertical stretch of scale factor 2, followed by a translation of 4 units left and 1 unit down is written as:
g(x) = 2*f(x + 4) - 1
<h3>
How to write the given transformation?</h3>
For a general function f(x), a vertical stretch of scale factor K is written as:
g(x) = K*f(x).
<u><em>Horizontal translation:</em></u>
For a general function f(x), a horizontal translation of N units is written as:
g(x) = f(x + N).
- If N is positive, the shift is to the left.
- If N is negative, the shift is to the right.
<u><em>Vertical translation:</em></u>
For a general function f(x), a vertical translation of N units is written as:
g(x) = f(x) + N.
- If N is positive, the shift is upwards.
- If N is negative, the shift is downwards.
So, if we start with a function f(x) and we stretch it vertically with a scale factor of 2, we get:
g(x) = 2*f(x)
Then we translate it 4 units left:
g(x) = 2*f(x + 4)
Then we translate 1 unit down:
g(x) = 2*f(x + 4) - 1
This is the equation for the transformation.

Answer:
<h2>
y = -3/2x + 9/2</h2>
Step-by-step explanation:
first let's convert the equation to y=2/3x+5
since the line is perpendicular we know that m=-3/2=1.5. now we just need to plug these numbers into an equation.
3=(-1.5)1+b
multiply.
3=-1.5+b
now add 1.5 to both sides of the equation.
4.5=b
change that into a fraction.
9/2.
now using 9/2 as b and -3/2 as m we have our equation:
<h2>
<u>y = -3/2x + 9/2.</u></h2>
He started at 418 above sea level. descended means he moved down so subtract 88 from 418:
418 - 88 = 330 feet.
He then climbed 120, so now add that to the 330:
330 + 120 = 450
He is now at 450 feet above sea level.
