Answer:
like real numbers, the arithmetic operations, such as addition, subtraction, multiplication and division are applicable to the rational numbers
Answer:
D
Step-by-step explanation:
this is because when multipled you get 0.3204 so u round and it becomes 0.320
Example:
This suggests two solutions,
and
.
However, upon plugging these solutions back into the equation, you get
which checks out, but
does not because
is defined only for
(assuming you're looking for real solutions only). So, we call
an extraneous solution, and the complete solution set (over the real numbers) is
.
First change the mixed fraction to an improper fraction.
-4 1/3 is -13/3 and
Then divide by -3/4. *Remember dividing by a fraction is really multiplying by its inverse.
So
-13/3 ➗-3/4 is
-13/3 ✖️-4/3= 52/9 ( note negative ✖️negative = positive)
52/9 simplified becomes 5 7/9
Answer:
f(5) does not equal 13.
Step-by-step explanation:
When we are given a function f(x), we can substitute any value for x as long as we change that value in the equation as well.
Therefore, if we are given f(5), we changed the x. Therefore, we also change the x in the rest of the equation. This would leave us with f(5) = 5² + 3. Now, we can just simplify.
f(5) = 5² + 3
f(5) = 25 + 3
f(5) = 28
Because we are asked to find if f(5) is equal to 13, we can see that 28 is definitely not equal to 13 and determine that this statement is false.
