Answer:
A. First equation by -2
Step-by-step explanation:
if you multiply the first equation by -2, the -4y cancels 4y
Answer:

Step-by-step explanation:
To solve, we need to take square root of both sides first:

Now we use the property of radical shown below to simplify square root of 28:
Property: 
Now, we have:

Now we take 4 to the other side and isolate x:

first answer choice is right.

Answer: C) 3</h3>
The rule we'll use is a^b*a^c = a^(b+c). So we add the exponents.
That means 5^n*5^3 = 5^(n+3)
So 5^n*5^3 = 5^6 turns into 5^(n+3) = 5^6
The bases are equal to 5, so the exponents be equal to one another.
n+3 = 6
n+3-3 = 6-3
n = 3
So 5^3*5^3 = 5^(3+3) = 5^6.
Answer:
b
Step-by-step explanation:
the answer is b because she gets paid 225 per week plus every sale so it going to be 245 she still needs 405 to get 650
