Answer:
Step-by-step explanation:
The function that we have to study in this problem is
The domain of a function is defined as the set of all the possible values of x that the function can take.
For a square-root function, there are some limitations to the possible value of the argument in the root.
In particular, the argument of a square root must be equal or greater than zero, because the square root of a negative number is not defined.
Therefore, in this case, we have to set the following condition for the domain:
And by solving, we get
which means that the domain of this function is all real numbers equal or greater than 5.
Answer:
y = 8x + 21
Step-by-step explanation:
The equivalent fraction to 8 1/3 is 25/3
Answer:
<em>n </em>+ 17 = 26
Step-by-step explanation:
<u>Let's replace the sentence with mathematical terms:</u>
17 more than a number is 26
More than means addition. The answer will also be a sum.
17 + a number is 26
Since the number is not specified, it will be represented by a variable. In this instance, the variable is <em>n</em>.
17 + <em>n</em> is 26
The equal sign will replace the word "is".
17 + <em>n</em> = 26
<u>Now, we can use the associative property of addition.</u>
17 + <em>n</em> = 26 into <em>n </em>+ 17 = 26
1 1/2 miles, this is because 20 minutes is 1/3 of an hour so we can multiply 1/2 by 3
