Which sets of numbers are closed under subtraction?

1 answer:

3 0

The answer is:

B.
rational numbers

Because if you perform subtraction in a set of rational numbers, the result you get would still be a rational number.

This does not apply to the other sets.

Is 50 tens 9 ones <,>,= 49 tens 35 ones

kati45 [8]

50 tens and 9 ones is less than 49 tens and 35 ones because 50 tens is 500 + 9 is 509, whereas 49 tens is 490 + 35.

Determine the vertical asymptote for the rational function f(x) = x - 4 over 2x - 3

k0ka [10]

Answer:

x = $\frac{3}{2}$

Step-by-step explanation:

Given

f(x) = $\frac{x-4}{2x-3}$

The denominator cannot be zero as this would make f(x) undefined.

Equating the denominator to zero and solving gives the value that x cannot be and if the numerator is non zero for this value then it is a vertical asymptote.

2x - 3 = 0 ⇒ 2x = 3 ⇒ x = $\frac{3}{2}$

Thus x = $\frac{3}{2}$ is the vertical asymptote
