Express 4x-1= 3 as a linear equation in two variables

olga nikolaevna [1]

Hello there!

~I hope you and your family are staying safe and healthy!

$4x - 1 = 3$

We need to start by saying that y = 3

$4x - 1 = y$ or $4x - y = 1$

Thus, the equation above is in the two variable form where y = 3

Thus, the required equation is $4x - y = 1$

Let me know if you have additional questions!

Fill in the blank to complete the following sentence. The two roots a +sqrt b and a- sqrt b are called ______ radicals.

katrin [286]

The two roots a + sqrt b and a - sqrt b are called conjugate radicals.

<u>Solution:</u>

Given that the two roots a + sqrt b and a - sqrt b are called ______ radicals.

Now let us write the each of the given two radicals in mathematical form.

So, first radical ⇒ a + sqrt b ⇒ $a+\sqrt{b}$ [ since sqrt means square root]

Now second radical ⇒ a - sqrt b ⇒ $a-\sqrt{b}$

We have to find the relation between $a+\sqrt{b} \text { and } a-\sqrt{b}$

Now, if observe $a+\sqrt{b}$ is conjugate of $a-\sqrt{b} \text { as }(a+\sqrt{b})(a-\sqrt{b})=a^{2}-b$

[ where radical is eliminated]

Hence, the two roots a +sqrt b and a- sqrt b are called conjugate radicals

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.
