F(x) = 25 - 2x
f(5) is pretty much the value of f(x) when x = 5
Plug x=5 into f(x)
f(5) = 25 - 2(5)
= 15
That's your answer.
Have an awesome day! :)
Answer:
C
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
Where m is the slope and (a, b) a point on the line
y - 4 = - 5(x + 3 ) ← is in point- slope form
with m = - 5 and (a, b) = (- 3, 4 ) → C
We can check this two ways: distributing the -0.5, and plugging in a number for x.
First, we can check this by distributing the -0.5. Our equation becomes:
-1.5x -2.5 = -1.5x + 2.5
Clearly, this is not true. We can show this one more time by plugging in a number for x. I will use 2.

Now, we evaluate both sides and see if they are equal.
-3 - 2.5 = -3 + 2.5
-5.5 = 0.5
Clearly, this is not true. These expressions are not equivalent.
We can find the sum of the interior angles of a regular polygon using the formula : (n-2) x 180, where n is the number of sides.
We replaced in : (24-2) x 180 = 3960
So, all the interior angles in this polygon add up to 3960.
-> Each interior angle is equal to 3960 : 24 = 165.
Answer:
$200
Step-by-step explanation:
63 mph is 13 mph more than 50 mph, so the fine will be that for 13 mph over the speed limit. The fine corresponding to 13 mph over the limit is $200.
