Answer:
1. All real numbers
2. All real numbers except y = 0
3. All real numbers except x = -7
4. All real numbers except b = 10
Step-by-step explanation:
For any function to be defined at a particular value, it should not be <em>approaching to a value </em><em> or it should not give us the </em>
<em> (zero by zero) form </em> when the input is given to the function.
The value of function will depend on the denominator.
Now, let us consider the given functions one by one:
1. 5y+2
Here denominator is 1. So, it can not attain a value or
<em> (zero by zero) form </em>
So, for all real numbers, the function is defined.
At y = 0, the value
So, the given function is <em>defined for all real numbers except y = 0</em>
<em></em>
<em></em><em></em>
Let us consider denominator:
x + 7 can be zero at a value x = -7
So, the given function is <em>defined for all real numbers except x = -7</em>
<em></em>
Let us consider denominator:
10-b can be zero at a value b = 10
So, the given function is <em>defined for all real numbers except b = 10</em>
<em></em>
<h3>Answer: 20.3</h3>
Work Shown:
tan(angle) = opposite/adjacent
tan(B) = AC/AB
tan(67) = x/8.6
8.6*tan(67) = x
x = 8.6*tan(67)
x = 20.2603303460843 ... make sure your calculator is in degree mode
x = 20.3 .... rounding to 3 significant figures

Answer:
A. -4
Step-by-step explanation:
Slope is rise over run, or y2-y1 / x2-x1.
<u>The slope is A. -4.</u>
Let's see--does that make sense? A slope of four would be pretty steep, and that matches the graph. It also should be negative because the line goes down and to the right, not up and to the right, so -4 makes sense!
