Answer:
a) The second is a subset of the first.
b) Neither
c) The first is a subset of the second.
Step-by-step explanation:
A set B is a subset of another one A if all the elements from the set B are part of the set A.
a) the set of airline flights from NewYork to New Delhi, the set of nonstop airline flights from New York to New Delhi: The second set is a subset of the first. It is obvious that all the nonstop airline flights from NY to ND are part of the airline flights from NY to ND.
b) the set of people who speak English, the set of people who speak Chinese. Neither. The people who speak english do not necessarily speak Chinese or vice versa.

The given quadratic equation is
We split the middle term to obtain
Factor by grouping;
Use zero product property;
QUESTION 3
The given system of equation is
If we multiply by 3, we obtain;
If we multiply by 4 we obtain;
Adding the last two equations will give us;
The y-variable is eliminated.
Answer:Multiply 3x+4y=−8
by 3. Multiply 7x−3y=6 by 4. Add the resulting equations together.
Answer:
1a the square root of 37
1b the same as a
2 y=3x+2
Step-by-step explanation:
a and b use the distance formula
for number 2 use rise over run to find the slope and find where the line intersects to find the y intercept.
Hope this helps :)
