Answer:
y=5
Step-by-step explanation:
The answer is 5 because that sign around the -5 is the absolute value sign. What the absolute value sign does is it measures the distance from 0 the number is. Since the number -5 is 5 units away from the number 0, then y=5.
7x 2. All the other answers equal 7x. The first one would be 49x. I hope this helps love! :)
Answer:
4th option
Step-by-step explanation:
She purchased a DVD for $28.
$50 - $28 = $22
1. 22 < 22
2. 22 > 22
3. 22 < 78
4. 22 > 78
I would say it would be the 4th option because she can only spend less than 78.
I can be very incorrect though, don't depend on me that much. Just make sure to think about my answer and what you would answer.
Answer:
0.625
Step-by-step explanation:
Just take a calculator and devide it
We want to convert this equation in terms of m, where 
While solving this problem, I instantly noticed the 
in the first term of the equation. Replace that with m.
Simplifying the rest is not as obvious. Using the distributive property, we can change ![[7x^2+21]](https://tex.z-dn.net/?f=%5B7x%5E2%2B21%5D)
to ![[7(x^2+3)]](https://tex.z-dn.net/?f=%5B7%28x%5E2%2B3%29%5D)
Do you see the "m" in here? Look again if you don't.
Now we can simplify the equation to 
and this cannot be simplified further.
I'm always happy to help someone who appreciates the help! :D
