Answer:
1. No.
2. Yes, there is no solution here.
Step-by-step explanation:
The former:
is our set of solutions.
The latter:
In other words, there is not any solution from the set of real numbers that suits us.
Answer: 3X+4 is the correct answer
Step-by-step explanation:
Pemdas, so exponent before multiply
so do a^-1/2 then multiply it by 2
remember that
and
therefor,
the we multiply by 2
Answer:
Step-by-step explanation:
First we need to write in correct form :
We know how to divide fractions. If we can divide numerator by numerator, denominator by denominator, we just do it. In this example we can not do that.
So, we rewrite first fraction and multiply by reciprocal second ( numerator and denominator change place)
Now, multiply numerator by numerator, denominator by denominator :
Answer:
10
Step-by-step explanation:
If we plug in any negative number as x, the result will always be greater than 4, which rules out answers A and B
lets try plugging in 4 as x to test answer C:
2(8-4)
2(4)= 8
8 is greater than 4, therefore C is wrong.
Lets try 10 as X (answer D):
2(8-10)
2(-2)
-4
We know that -4 is less than 4, therefore it makes the inequality true! :)
