Answer:

AC = 7

Step-by-step explanation:

1. Draw out the line and label everything you know.

2. By observation, we know that AD is also equal to AC + CD.

3. To find CD, take the length of BD (12) and subtract it by the length of BC (4): 12 - 4 = 8. The length of CD is 8.

4. Finally, to find AC, subtract the length of CD (8) from AD (15): 15 - 8 = 7. The length of AC is 7.

For x < -2 f(x) = -3x - 3 6x – 28 for Find f(5)

Lemur [1.5K]

Answer:

f(5) = 2

Step-by-step explanation:

To evaluate f(5), that is when x = 5 in the interval x ≥ 5

then

f(5) = 6x - 28 = 6(5) - 28 = 30 - 28 = 2, so

f(5) = 2
