Answer:
B. x < -8 or x > 8
Step-by-step explanation:
You can use process of elimination to solve this problem by going through every solution and testing them out, but let's jump right to B.
Process:
You know that since the inequality states that x^2 has to be greater than 64, x has to be more than 8, or less than -8.
This is because 8^2 = 64, and -8^2 = 64, and the inequality requires the answer to be more than 64.
Looking at B., you can see that if x is < -8, the square of, for example, -9, would be 81. This is greater than 64, so this works!
Now, B. also has an alternative. The 'or' is a major clue to which is the correct answer, since the square root of any number can be positive or negative. (-8^2 = 8^2)
The 'or' states that x must be greater than 8. So, for example, if we take the square of 10, we get 100, and that is also greater than 64.
We've proven that this solution is accurate for both parts, so it is definitely the one we want!
Hope this helps!
Answer:
The first blank is: 26
The second blank is: 17
The third blank is: 31 - n
Step-by-step explanation:
So basically each row should add up to 31. So for every number they give you (doesn't matter which color ball), you need to subtract it from 31.
That's why for the first blank, 31 - 5 is 26
second blank, 31 - 14 is 17
and so on....
so the resulting function would be 31 - n
n being a random number that is given to you
