Answer:

The value of x=6

Explanation:

Given:

$\frac{1}{2}(4x+16) =20$

Now we will do cross multiply on both sides of the equation

$1\times(4x+16)=20\times2$

(4x+16)=40

Now we will solve the above equation

$4x+16-40=0$

$4x-24=0$

$4x=24$

$x=\frac{24}{4}$

$x=6$

Hence the required value which satisfy the given equation of the question is x=6.

Which situation represents a multiplicative relationship? A) Kevin is 8 years older than his brother Sean. B) For every cat at t

Lunna [17]

Answer:

Option B represents a multiplicative relationship.

Step-by-step explanation:

We are required to find the situation that represents a 'multiplicative relationship'.

According to the options, we have,

A) Kevin is 8 years older than his brother Sean.

This gives us the relation that, Kevin's Age = 8 + Sean's Age.

Thus, this is not a multiplicative relationship.

B) For every cat at the pet store, there are 2 dogs.

We get that, for 1 cat, there are two dogs.

So, Number of dogs = 2 × Number of cats.

Thus, this is a multiplicative relationship.

C) A buy one get one free sale on sweaters at the clothing store.

So, during the sale a person can buy 1 + 1 i.e. 2 sweaters.

Thus, this is not a multiplicative relationship.

D) James always keeps $100 more in his savings than his checking account.

This gives us the relation that, Savings balance = 100 + Checking balance

So, this is not a multiplicative relationship.

Hence, option B represents a multiplicative relationship.

Use graphs and tables to find the limit and identify any vertical asymptotes of the function.

scZoUnD [109]

Answer:

The line x = 8 is our vertical asymptote

The limit of $\frac{1}{x-8}$ as x approaches 8 from the left is negative infinity; -∞

Step-by-step explanation:

We have been given the following function;

$\frac{1}{x-8}$

Considering that the function is rational, it will defined everywhere on the real line except where the expression in the denominator will be 0;

That is the function will not be defined where;

x - 8 = 0

solving for x yields;

x = 8

The function will be approaching the vertical line x = 8 asymptotically, meaning that the function will never touch or cross this line. We can therefore say that,

The line x = 8 is our vertical asymptote for the given function

The limit of $\frac{1}{x-8}$ as x approaches 8 from the left;

$\lim_{x \to8^{-} }\frac{1}{x-8}$

For x approaching 8 from the left, $x$ which implies that $x-8$

The denominator will be a negative quantity approaching 0 from the left, that is -∞.

Thus;

$\lim_{x \to8^{-} }\frac{1}{x-8}$ = -∞
