2.2 as an improper fraction is 11/5
Answer:
92
Step-by-step explanation:
Please use " ^ " to indicate exponentiation, ok? Thank you.
If
ƒ(x) = 9x^2 + 27x + 2, and we are to find ƒ(2), substitute 2 for x"
f(2) = 9(2)^2 + 27(2) + 2
This becomes:
f(2) = 36 + 54 + 2 = 92
Answer:
4%
Step-by-step explanation:
We can write the following equation:
20 * (x / 100) + 60 * 0.12 = 80 * 0.10 (Note that since we're writing the percentages as decimals, x% becomes x / 100 as a decimal.)
x / 5 + 7.2 = 8
x / 5 = 0.8
x = 4%
