Answer:
If f(x) = 5x + 40, what is f(x) when x = –5 (D)
What is the inverse of the function f(x) = 2x – 10? (B)
Step-by-step explanation:
Answer:
it is 2 1/10 i took the test from K12
Step-by-step explanation:
A/B is a reduced fraction which can be represented as a
terminating decimal if and only b is of the form 2^n5^n where m and n are non
negative integers. For example: 7/250, the terminating decimal here is 0.028 as
250 as the denominator equals to 2*5^2.
According to the above, we must know whether the denominator
have only 2-s and or 5-s as the prime factors. So,
Q = 8 = 2 ^3 = hence the denominator has only 2 prime
factors. Fraction P/Q will be termed as terminated decimal which is sufficient.
