If f(x)=-4x+8, what is f(2.5)?
2 answers:
Answer: f(2.5) = -2
Step-by-step explanation:
To find f (2.5) means we substitute 2.5 into x in the given equation:
F (2.5) = -4 (2.5) + 8 .....multiply 2.5 by -4, then add.
F(2.5) = -10 + 8
F(2.5) = -2
I hope this helps.
The explanation the person gave is correct but the answer is -2. Since it’s -10+8=-2 bc the 10 is a negative...

Answer:
66 inches
Step-by-step explanation:
v² = 55² + 26² - 2(55)(26) · cos 103°
v² = 3025 + 676 - [2860 · cos 103°]
v² = 3701 - (-643.4)
v² = 4344.4
v = ≈ 66
