Answer: Tyler used the distributive property.
Step-by-step explanation:
For the expression:
Madison wrote: which is by commutative property of addition.
The commutative property of addition says that , for a,b be any real number
Tyler wrote: which is by distributive propery.
The distributive property says that , for a,b,c be any real numbers.
Hence, the last option is correct.
Answer:
given below.
Step-by-step explanation:
BAC = 80 degree
AZC = 80 degree
BZE = 80 degree
ZCE = 40 degree
CZE = 40 degree
2x+x=105
3x=105
The answer is A
Answer:
f(x)= -0.4x+107
Step-by-step explanation:
This is a fairly easy half-life problem
Each half-life reduces the radioactive material by one half.
So after 72 hours the radioactive material would have undergone 6 half-lives.
2^6 = 64.
So, there will be one sixty-fourth of the material left.
520 / 64 = 8.125 grams will remain.
radioactive decay is an exponential decay function.
