Answer: The answer is 5x+6
Step-by-step explanation:
1/3(9x+16+2)+2x
= 1/3(9x)+1/3(16)+1/3(2)+2x
=3x/1+16/3+2/3+2x/1
=3x/1+2x/1+16/3+2/3
Take the L.C.M
=3x+2x/1+16+2/3
=5x/1+18/3
=5x+6
Answer:
A) -15
Step-by-step explanation:
The average rate of change of f(x) on interval [a, b] is given by ...
(f(b) -f(a))/(b -a)
Here, you have ...
f(x) = -2^x +70
[a, b] = [2, 6]
so the average rate of change is ...
(f(6) -f(2))/(6 -2) = ((-2^6 +70) -(-2^2 +70))/4 = (-64 +4)/4 = -16+1
average rate of change = -15
Answer:
A
Step-by-step explanation:
got it right
The rate of growth in the tree is 4 feet per year.
Height of tree at year 0 = 2 feet
Height of tree at year 1 = 6 feets
Height of tree at year 0 = 10 feets
Therefore, the difference in the heights of the tree from the previous year will be:
= 6 feet - 2 feet.
= 4 feet
In conclusion, the correct option is B.
