Which of the following statements would be correct to use when proving that limx→4(3x−4)=8?

Fudgin [204]

Answer:

Option c

Step-by-step explanation:

given that limit x tending to 4 of the function (3x-4) is 8

This implies for all values of x such that for epsilon >0 arbitrary small ,

$||x-4||$ , we get

|f(x)-8|<3epsilon

this is equivalent to the option c.

Proof:

Consider

$||x-4||$

Hence it follows that option C is right.

Which expression is equivalent to Negative 2 and one-fourth divided by negative two-thirds?

disa [49]

Negative 2 and one-fourth divided by negative two-thirds is equivalent to $\frac{-2+\frac{1}{4}}{-\frac{2}{3}}$ and simplified into $=\frac{21}{8}$

Step-by-step explanation:

We need to find the equivalent expression of Negative 2 and one-fourth divided by negative two-thirds

Basically we will translate it into mathematical form.

Converting step by step

Negative 2: -2

and: +

one-fourth: 1/4

combining them we get:

Negative 2 and one-fourth: $-2+\frac{1}{4}$

divided by negative two-thirds: $\frac{-2+\frac{1}{4} }{-\frac{2}{3} }$

So, Negative 2 and one-fourth divided by negative two-thirds is equivalent to: $\frac{-2+\frac{1}{4} }{-\frac{2}{3} }$

We can simplify the term $\frac{-2+\frac{1}{4} }{-\frac{2}{3} }$ to get simplified answer.

Simplifying:

$\frac{-2+\frac{1}{4}}{-\frac{2}{3}}$

Taking LCM of numerator

$=\frac{\frac{-2*4+1}{4}}{-\frac{2}{3}}$

$=\frac{\frac{-8+1}{4}}{-\frac{2}{3}}$

$=\frac{\frac{-7}{4}}{-\frac{2}{3}}$

Converting division into multiplication and reciprocating the denominator

$=\frac{-7}{4}\times -\frac{3}{2}$

$=\frac{-7*-3}{4*2}$

$=\frac{21}{8}$

So, Negative 2 and one-fourth divided by negative two-thirds is equivalent to $\frac{-2+\frac{1}{4}}{-\frac{2}{3}}$ and simplified into $=\frac{21}{8}$
