The first step of Elimination in solving a system is to find opposites of one of the variable terms. Explain in your own words,
vovikov84 [41]
You need to find opposite terms when using the elimination method to solve a system of equations so that way you can find out the y or the x after you have crossed out the fraternal twins. You have to get rid of either the y or x in order to work it out and find the y or x value.

So this is a bit confusing. I don't know if you need me to solve them then simplify or just reduce them but I will try to write it anyways.

1. (4^{3} )^5
For this, you can just multiply 3 by 5 which is 15 then place it as an exponent as 4^{15}

But if you need to solve it, you multiply 4 by itself 15 times which is107,3741,824 but I don't think thats what you are looking for but here it is anyways

I assume that it was the former that was the answer

Answer: 4^{15}

2. 4^{-2}

When dealing with negative exponents, you get one and divide by the base according to the exponent. It says -2⇒2 which means you divide 1 by 4, twice

1÷4÷4=.0625

Answer: .0625

3. 4^3

Since its positive, you multiply by the base number (rather than divide if it was negative)

So it is 4×4×4=64

Answer: 64

4. 4^8

Here, you just take what I did in step 3 and multiply by the base number according to the exponent

4×4×4×4×4×4×4×4=65,536

Answer: 65, 536

5. 4^{15}

You do what you did in the previous steps but multiply the base 15 times


4×4×4×4×4×4×4×4×4×4×4×4×4×4×4=1,073,741,824

Answer: 1,073,741,824


If you don't know what to do, go and ask your teacher because he/she would know best on what to do :-)

We can simplify this problem by pairing like terms together.

9x + 15x - 2x + 2
22x + 2

This expression can be simplified down to
22x + 2

True or False: If your friend wants to take 6 hours for the 300 mile drive and you want to take 6 hours for the 240 mile drive,
Mila [183]

Answer: I'm pretty sure this is false.

Step-by-step explanation:

If you are driving the same amount of time as your friend, then you travel the same distance, unless you are going different speeds. The person that travels the most amount of distance would be going faster, in this case your friend.

Please don't quote me on this, I only THINK this is right, not 100%
