Answer:
The tree grows 3,14 centimeters per year
The mean of the students scores is 81.3, the median is 80.
If Ms.Mosher adds 5 bonus points to each student, the mean and median will both increase by 5 of the six student’s scores!
If f(x)= 3x+2 and g(x)= 4x, then
f(x)+g(x) = 3x+2+4x
= 7x+2
For f(g(x)), you work from the inside and work your way out. Another way of thinking is to go from right to left. (Inside/out and right/left are the same simply using different wording).
So what is g(x)? 4x.
Now, you take 4x and plug it into the f(x).
** Math--> English translation:
Look at the f(x) equation. Wherever you see an x in the f(x), replace the x with 4x [because 4x is the g(x)]. Basically, plug the g(x) into f(x).
So:
f(g(x)) becomes
f(4x) becomes
3 (4x)+2 = 12x+2
** Disclaimer: Notation may be inaccurate.
That's your answer. (Usually you leave it as so, but if your instructor wants it factored, then proceed).
As for the third part, I am unsure of a clear answer, so I am unable to provide an answer at the time.

Answer:
y = -2x -3
Step-by-step explanation:
I love slope-intercept form! lol
y =mx +b
so we have 2 points given: (-1,5) and (4,-5)
to find the SLOPE of the slope-intercept form, we need to subtract and divide
(-5-5)/(4+1)
-10/5= -2 which is our slope
now! lets translate this info into point slope form. y - y1 = m (x - x1)
(-1,5) and we kno the slope is -2.
y - 5 = -2 (x - (-1))
y-5 = -2(x + 1)
y-5 = -2x -2
add five
y = -2x -3 we are back to slope intercept form! YAY!
