Answer:
Step-by-step explanation:
Given equation:
Solving for unknown variable
Adding 8 both sides by additive property of equality.
Squaring both sides to remove the square root.
Adding 5 both sides by additive property of equality.
Dividing both sides by 6 to isolate
∴
Answer:
Slope of the line DV = -1
Step-by-step explanation:
Let point D (-5, 1) be
Let point V (-1, -3) be
Plug in the appropriate values,
slope equals -1
Here we get the statement:
"sec^-1(0.5) is undefined"
And we want to see if this is true or false, so let's use the properties that we know to find that this is false.
Remember that the sec function is defined as:
Then we will have:
Then is really trivial to see that:
Then we can conclude that the function is not undefined at 0.5, so the statement is false.
Below you can see the graph of the given function, and you will see that it is never undefined.
