Answer:
f(5) = 5
Step-by-step explanation:
F(x)=x^2 - 4x
Let x = 5
F(5)=5^2 - 4*5
= 25 - 20
= 5
Answer:
I did this exact same question on USATestPrep and here's what I answered that I got correct:
B, C and this one isn't an answer choice but the additional answer was: "1,000 grams of radioactive material with a half-life of 6 hours."
Hope this helps! I'm sorry if it doesn't help future people who sees this :/
7 7/8 - 3 3/8 =
49/8 - 9/8 =
49-9/8 =
40/8 =
5
X/(2x + 1) + 1/4 = 2/(2x + 1)...multiply all terms by 2x + 1 and cancel out
x + (2x + 1)/4 = 2
3/2x + 1/4 = 2
3/2x = 2 - 1/4
3/2x = 8/4 - 1/4
3/2x = 7/4
x = 7/4 * 2/3
x = 14/12 = 7/6 <==
