Ronch [10]3 years ago

Answer:

a) -4/3

b) 8

c) -2/3

d) 2

Step-by-step explanation:

In all four cases replace the value of "x" in the function's expression, and evaluate to find the numerical answer:

a) f(\frac{1}{4}) = \frac{1}{\frac{1}{4}-1 } =\frac{1}{\frac{1}{4}-\frac{4}{4}  }= \frac{1}{-\frac{3}{4} } = -\frac{4}{3}

b) g(\frac{1}{4} ) = \frac{1}{\frac{1}{4} } +4 = 4 + 4 = 8

c) f(-\frac{1}{2}) = \frac{1}{-\frac{1}{2}-1 } =\frac{1}{-\frac{1}{2}-\frac{2}{2}  }= \frac{1}{-\frac{3}{2} } = -\frac{2}{3}

d) g(-\frac{1}{2} ) = \frac{1}{-\frac{1}{2} } +4 = -2 + 4 = 2

100 is divisible by which of the following numbers 2,3,4,5,6,9 or 10?
pochemuha
The correct answer is B: 2,4,5, 10

We know that 100 is not divisible by 3 because 100/3 is 33.33 repeating, which is an irrational number.

We also know that 100 is not divisible by 6 because 100/6 is 16.66 repeating which is also an irrational number.

100/2=50 (rational)
100/4=25 (rational)
100/5=20 (rational)
100/10=20 (rational)

Hope this helps!
