Answer:
Q
Step-by-step explanation:
X has constant value
x'-x = 0
m =(y'-y)/(x'-x) --> undefined
If we have a function f(x), f(5) is f(x) but replacing x with 5. The result give us a value of y and a point of the function, (x, y).

ANSWER A
A fisherman travels downstream at full speed to his favorite fishing spot.
<span>The stream is running at a rate of 5 miles per hour, and he takes an hour to get to the fishing hole. </span>
<span>He catches 5 fish and calls it a day. </span>
<span>He takes twice as long at full speed to get back to the dock going against the current. </span>
<span>(x + 5)/(x - 5) = 2 </span>
<span>x = 15
</span><span>The full speed of the fishing boat is 15 miles per hour.</span>
That's not an equation. It's just an expression that stands for a number.
Of course, we can't find the number until we know what 'm' and 'n' are.
The largest "common factor" is 3mn .
So in factored form, the expression is 3mn (m + 4n) .
Answer:
D
Step-by-step explanation:
For this question, we know that x represents the thousands of square feet in the stadium. We also know that the stadium is 18 thousand square feet. Therefore, the amount of thousands of square feet, or x, is 18. We can then plug 18 in for x in the equation, getting

as our cost
