Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 3x² - 7x
f(-2) is x = -2
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: f(-2) = 3(-2)² - 7(-2)
- Exponents: f(-2) = 3(4) - 7(-2)
- Multiply: f(-2) = 12 + 14
- Add: f(-2) = 26

Answer:
The distance between Harry’s home and his office? is 15 miles.
Step-by-step explanation:
The speed, distance time formula is:

Given:
Speed (<em>s</em>) = 30 miles/hour
Then the relation between distance and time is:

If Speed was 60 miles/hour the time taken is
hours.
Then the relation between distance and time is:

Use the value of <em>d</em> = 30t in (ii)
<em />
<em />
Determine the distance as follows:

Thus, the distance between Harry’s home and his office? is 15 miles.
