f(x) = 2x - 3, for f(x) = 13
13 = 2x - 3
Add 3 to both sides.
16 = 2x
Divide both sides by 2
8 = x
Answer:
undefined
Step-by-step explanation:
Sin(x) = 0 where x = 0
Cos(x) = 1 where x = 0
Cot(0) is undefined

Answer: A. 397 miles
Step-by-step explanation:
Add the miles traveled on Saturday and Sunday to find out how many miles were traveled in total.
409 + 239 = 648
Now, subtract the total number of miles traveled from the original distance.
1,045 - 648 = 397
We have that
(x + 3)² = -20(y − 1)
<span>This is actually the vertex form, so we can obtain the vertex already
</span>the vertex is the point (h,k)------------> (-3,1)
4p=-20------------> p=-5
Focus is at (-3,1-5)---------> (-3,-4)
Directrix is at <span>y = 1-(-5)----------> y=6
</span>
the answer is
the directrix is y=6
