<u>Use intersecting chords theorem:</u>

- 5(5x + 2) = 10(6)
- 5x + 2 = 12
- 5x = 10
- x = 2

**Answer:**

f(x) is reflected over the x-axis and vertically scaled by a factor of 3

**Step-by-step explanation:**

If you compare the two functions, you see that ...

g(x) = -3f(x)

Multiplication by -1 effects a reflection over the x-axis. (All y-values are transformed to their opposite.)

Multiplication by 3 is a vertical scaling by a factor of 3.

Taken together, **f(x) is reflected over the x-axis and vertically scaled by a factor of 3**.

**Answer:**

**Step-by-step explanation:**

Since, we have to change

inches / sec to feet/ min

It means that

we have to change

inches to feet

and sec to min

we know that

and

so, we will use these two factors only

Cross multiply the fractions as in 20 times D and 13 times 60 and the problem will be 20d = 780. Here you can divide 780 by 20 and the answer is what D equals to.
