Answer:
(f - g)(x) = -x + 8
General Formulas and Concepts:
- Order of Operations: BPEMDAS
Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 2x + 1
g(x) = 3x - 7
(f - g)(x) = f(x) - g(x)
<u>Step 2: Simplify</u>
- Set up: (f - g)(x) = (2x + 1) - (3x - 7)
- Distribute -1: (f - g)(x) = 2x + 1 - 3x + 7
- Combine like terms: (f - g)(x) = -x + 8
0 times 0 . sorry if it’s wrong
91 and 1 your welcome bye
f(2.5) means x is equal to 2.5.
Replace x in the equation with 2.5 and solve:
6(2.5) + 1.5 = 15 + 1.5 = 16.5
f(2.5) = 16.5
Answer:
In 1 second he runs 6.0 meters.
Step-by-step explanation:
The question asks "how far does he run in one second?" The answer is a distance, not a time, so if it needs to be rounded, it is to the nearest tenth of a meter.
Divide the distance by the time:
(414.2 m)/(68.7 sec) = 6.029 m/sec
In 1 second he runs 6.0 meters.
