Answer: D. -4F
Step-by-step explanation:
Let's use simple math. 1 - 5 = -4 or -8 divided by 2 = -4, right?
Same idea, so now lets apply it.
If it decreases -8F in only two hours you just simply divide the temperature by the hour.
Looking at problem A that just would not make sense, how could it decrease while staying at the same number?
Problem B also wouldn't make sense because a negitive plus negitive equals a negitive, same with subtracting. So 10 is inncorrect
Problem C also is inncorrect because 8 divided by 2 = 4, not 6
So, D is correct because -8 divided by 2 equals = -4
Hope this helps!
Answer:
No
Step-by-step explanation:
Given that:
Amount earned when a student does comminty service = $5
Number of students in club = 12
Amount earned E, is a function of number of members (n) who does community service.
Hence,
E = n * amount earned per member
Is 24 a possible output?
To test, then E = 24
24 = n * 5
24 = 5n
24/5 = 5n/5
4.8 = 5
Hence, 24 is not a possible output, be use number of membwra cannot be a decimal

Answer with Step-by-step explanation:
We are given that a group H= b consisting of the set of all strictly positive real numbers with binary operation given by multiplication.
We have to show that H is isomorphic to (R,+) where (R,+) is a group consisting of real numbers with binary operation given by addition.
Isomorphic group :If there is one-one correspondence between the elements of two group with respect to given binary operations and there exist an isomorphism between two groups then the groups are called isomorphic groups.
Suppose a function
f:
f(x\cdot y)=f(x)+f(y)
If two groups have same order and have same order elements then we also says that the groups are isomorphic.
Order of H is infinite and order of (R,+) is also infinite.
H have one element of order 1 and one subgroup of order of order 1 and (R,+) have one element of order 1 and one subgroup of order 1.
(R,+) is infinitely generated and and H is also infinitely generated group.
Both have same properties .Hence , H and (R,+) are isomorphic group.
